CSV files, or comma-separated values, are a common way to store and share tabular data. They're often used to store time-related information, which can be represented using different formats. However, to effectively analyze and manipulate this data, converting timestamp columns into DateTime format is essential.
DateTime is a data type that represents both date and time information in a unified manner. It enables efficient manipulation and analysis of time-series data, facilitating tasks such as filtering, aggregation, and comparison.
The word "Timestamp" usually refers to the Epoch Unix Timestamp. Which is the number of seconds between the Unix Epoch (00:00:00 UTC on 1 January 1970) and a particular date.
In this guide, you'll learn how to parse and convert a CSV column with timestamp values into DateTime format. The guide focuses on the "Unix Timestamp" format, but the tool works with many other DateTime string representations.

Step 1: Load your CSV file
First, upload your CSV file to Datablist. The CSV to vCard feature is accessible without needing to register. As an anonymous user, you can import CSV files with up to 10,000 rows. For larger files, create a free account. Registered users can import CSV files with up to 1.5 million rows.
To get started, create a new collection by clicking the &ampquot;+&ampquot; button in the left sidebar, then select &ampquot;Import CSV&ampquot; to upload your file.
Import CSV file
In just a few seconds, your CSV columns and data will appear in Datablist, ready for you to work with.
Step 2: Map your columns to vCard fields
Now your CSV is loaded, converting the data to vCard is simple and can be done in just a few steps.
Click on the Export button available in the application header.
Export CSV to vCard
In the export options, choose the vCard format. This ensures your contacts are saved in a format compatible with most modern devices and apps.
Select vCard (VCF) data format
The next step is to match your CSV columns (like Name, Email, and Phone) to the corresponding vCard fields. This ensures all your data is accurately transferred.
The vCard format is a standard for electronic business cards. The format includes a list of standard properties to store the name, the profile picture, email addresses, etc.
Visit the vCard Wikipedia page to see all available vCard properties.

The format also allows custom properties to store any data other than the standard ones.
Advice: To improve the compatibility of your exported VCF file (vCard) with other tools, be sure to map your CSV column with a standard property when possible. Use custom property only when no matching property exists.

Datablist lists all your CSV columns.
For each of them:
Select a standard vCard property
Or define a custom property

Map your CSV columns with vCard fields
When selecting &ampquot;Map with custom vCard property&ampquot;, an input appears. Write the name of the property to be added in the exported vCard file (.vcf).
Custom vCard property
Once you&amp#39;ve mapped the fields, you’re ready to export and use your contacts in the vCard format!
Just click on the &ampquot;Export&ampquot; button at the bottom of the export modal.
A file is generated with the .vcf file extension. All your CSV rows are converted to the vCard format.
Conclusion: vCard is a good text format for storing and exchanging contacts between tools. With its powerful features to view and edit CSV, Datablist is the perfect tool for converting your contacts from a CSV file to a VCF file.
FAQ
What is the version of vCard generated?
Datablist sets the vCard version to the last available to date: VERSION:4.0.
It also adds the KIND property to individual to define the type of entity to contacts.
How many contacts be converted at once?

CSV stands for "Comma Separated Value(s)" and is a format to store structured data using text files. In a CSV file, each line is a data record. And each record is made of fields separated by commas (or sometimes by semicolons ";" or tabular keys).
CSV files are a common way to transfer data between applications. Because it relies on text files, the CSV format is a simple way to export database or spreadsheet data.
Unfortunately, the CSV file format is not standardized. Encoding format, delimiters, or escaping rules might differ between implementations. As a result, most applications accepting CSV files as data sources have different options to read the CSV data.
To view the content of an CSV file, you can uses an online <a href="/csv-editor">CSV editor</a> that is compatible with CSV exported by most applications.

A CSV file is a text file used to store structured data. The CSV format is used to transfer structured data between applications or to export data in order to perform data analytics.
The first use case is data transfer. Applications such as e-commerce software, mailing list providers, or CRM deal can import and export data in the CSV format. In e-commerce software, it is common to import a CSV containing the product catalog. When managing a mailing list, importing a CSV with all the email addresses is faster than adding each contact one by one.
The second use case is data analytics. The CSV format is flat and is perfectly compatible with spreadsheet or data analytics tools. As a result, it is a good source to analyze and visualize data. A CSV file has no size limit and can contain millions or more of records. It is a good file format to use in Big Data.

The second use case is data analytics. The CSV format is flat and is perfectly compatible with spreadsheet or data analytics tools. As a result, it is a good source to analyze and visualize data. A CSV file has no size limit and can contain millions or more of records. It is a good file format to use in Big Data.


Dedupe is a synonym for data deduplication or de-duplicate. Dedupe is the process of eliminating duplicate entries from a data set.
The term is used both in computing and for non-technical people.
In computing, deduping is performed in software development to remove duplicates in a list. Still with computing, data deduplication is used with files too. In a system that store files, deduplication is a technique to list all similar files and their reference in documents, emails, etc., and to remove all redundant files to keep only one version and have all references point to those single files.
Dedupe is also used for non-technical people to define the action of finding and merging redundant duplicates. A good example is CRM deduplication. CRM applications store contact information for leads, customers, etc. Several CRM records can represent the same person or business and hold different and complementary data. In this example, <a href="/features/duplicates-remover">merging duplicates</a> in the CRM is important to build a single view for every user. It also lower software cost as it reduces the number of items to store in a database.

Join and Merge are two operations to combine data from several files. When merging, you are combining several files with the same structure into a single listing.
When joining, you are combining several files with different data structure but with at least one common field. This common field will be used as a key to combine the data and generate a single listing combining the fields from all the files.
<h2 id="user-content-merge-and-join-examples"><a href="#merge-and-join-examples" aria-hidden="true" tabindex="-1"></a>Merge and Join examples</h2>
<h3 id="user-content-merge-example"><a href="#merge-example" aria-hidden="true" tabindex="-1"></a>Merge example</h3>
Let's say you have a File A:
<pre><code> firstName | lastName | jobTitle
 Jean | Doe | CEO
 Morgan | Stanlet | Marketing Officer
</code></pre>
And a File B:
<pre><code> firstName | lastName | jobTitle
 Joe | Kanigan | Finance
 Marie | Filman | Dev
</code></pre>
Then, the resulting of a merge operation would be:
<pre><code> firstName | lastName | jobTitle
 Jean | Doe | CEO
 Morgan | Stanlet | Marketing Officer
 Joe | Kanigan | Finance
 Marie | Filman | Dev
</code></pre>
<h3 id="user-content-join-example"><a href="#join-example" aria-hidden="true" tabindex="-1"></a>Join example</h3>
Now, let's look at the join operation. When performing a join, your files can have different structures but must have a common identifier that will be used to combine the data together.
We have a File C:
<pre><code> email | jobTitle
 jean.doe@gmail.com | CEO
 morgan@gmail.com | Marketing Officer
</code></pre>
Than we want to join with a File D:
<pre><code> email | City
 jean.doe@gmail.com | Paris
 morgan@gmail.com | New York
</code></pre>
The resulting join operation using the <code>email</code> identifier is
<pre><code> email | jobTitle | City
 jean.doe@gmail.com | CEO | Paris
 morgan@gmail.com | Marketing Officer | New York
</code></pre>
A very common data manipulation task is to bring two or more sets of data together based on a common key.


Join and Merge are two operations to combine data from several files. When merging, you are combining several files **with the same structure** into a single listing.

When joining, you are combining several files **with different data structure** but with at least one common field. This common field will be used as a key to combine the data and generate a single listing combining the fields from all the files.


## Merge and Join examples

### Merge example

Let's say you have a *File A*:

```
  firstName |    lastName    |  jobTitle
    Jean    |       Doe      |  CEO
   Morgan   |     Stanlet    |  Marketing Officer
```


And a *File B*:

```
  firstName |    lastName    |  jobTitle
    Joe     |     Kanigan    |  Finance
   Marie    |     Filman     |  Dev
```

Then, the resulting of a merge operation would be:

```
  firstName |    lastName    |  jobTitle
    Jean    |       Doe      |  CEO
   Morgan   |     Stanlet    |  Marketing Officer
    Joe     |     Kanigan    |  Finance
   Marie    |     Filman     |  Dev
```


### Join example

Now, let's look at the join operation. When performing a join, your files can have different structures but must have a common identifier that will be used to combine the data together.

We have a *File C*:

```
          email           |      jobTitle
    jean.doe@gmail.com    |        CEO
     morgan@gmail.com     |    Marketing Officer
```

Than we want to join with a *File D*:

```
          email           |         City
    jean.doe@gmail.com    |        Paris
     morgan@gmail.com     |       New York
```

The resulting join operation using the `email` identifier is

```
          email           |      jobTitle         |       City
    jean.doe@gmail.com    |        CEO            |       Paris
     morgan@gmail.com     |    Marketing Officer  |      New York
```

You can download sample CSV files here for testing purposes. The datasets can be used in any software application compatible with CSV files. An easy tool to edit CSV files online is our CSV Editor.
Three datasets are available: Customers, People, and Organizations.
For each dataset, several CSV sizes are available, from 100 to 2 million records. The first line contains the CSV headers. An index column is set on each file. Rows have an index value which is incremental and starts at 1 for the first data row.
All datasets are free to download and play with. All the data is random and those files must only be used for testing.
The script used to generate all those CSV files is open source and available on Github.

grep -i -E "keyword1|keyword2" filepath.csv | wc -l
```


## Get the number of rows of multiple CSV files

To have the sum of the rows of all the CSV files in the current folder, use the following command:

```
cat *.csv | wc -l
```

![Get the sum of all csv files](/learn_images/csv/words-count/sum-rows-csv-files.png#1336x518)



To view the content of your CSV file, you can uses an online [CSV editor](/csv-editor).


Count the number of rows of a CSV file on Linux or macOS Terminal

Open the Terminal. (on macOs, you can use Spotlight with keyboard shortcut ⌘ + Space)
Open Terminal using Mac Spotlight
Move terminal working directory to the folder containing your CSV file. Use ls to show current directory files and folders and cd to move inside a folder.
Enter the following command. Replace filepath with your CSV file path:wc -l filepath.csv

The line count will be printed before the file name
Word Count Command

 The wc command is used to count the number of words or lines (with the -l option) in a file. In a CSV file, each line is a data record. Counting the number of rows is an easy way to have the number of records in your CSV file.
Get the number of rows containing a keyword in a CSV file
If you want to filter rows in your CSV file and count the matching lines, combine wc with the command grep.
grep &quotkeyword&quot filepath.csv | wc -l
Filter and Count Lines
You can also search for multiple keywords with grep using a regular expression (the -E option is for --extended-regexp). Any line with at least one of the keywords will be counted.
grep -E &quotkeyword1|keyword2&quot filepath.csv | wc -l
Filter and Count Lines with multiple keywords
By default, grep is case sensitive (uppercase and lowercase characters are distinct). To ignore case in the search, add the -i (for --ignore-case) in your command:
grep -i &quotkeyword&quot filepath.csv | wc -l
or
grep -i -E &quotkeyword1|keyword2&quot filepath.csv | wc -l
Get the number of rows of multiple CSV files
To have the sum of the rows of all the CSV files in the current folder, use the following command:

Few <a href="/csv-editor">CSV editors</a> can manage large CSV files. Spreadsheet tools like Excel and Google Sheet break before reaching the million of lines. And dedicated tools target data scientists so they are expensive and complex to use.
A free alternative is to use your terminal and manage your big CSV file using the command line.
A CSV file is a text file, with each line being a data record. And each record is made of fields separated by commas (or sometimes by semicolons ";" or tabular keys). Because a CSV file is a text file and each line is a record, you can use Linux/Unix commands for manipulating texts.
The command line might seem scary but they are also very powerful. I'm listed here the command I use to search in big CSV files.

<h4 id="user-content-search-for-whole-keyword"><a href="#search-for-whole-keyword" aria-hidden="true" tabindex="-1"></a>Search for whole keyword</h4>
To avoid unexpected results like that, you can switch to Regular Expression (RegEx) and search for the whole keyword.
By adding the -E option to grep, I tell grep to interpret the pattern as a regular expression. And I add \b before and after my keyword. \b is a RegEx operator that means word boundary.

To search for lines in your CSV file that have all the requested keywords, you can use another command: awk. Awk is another command tool to deal with text files. It has more advanced features.
Awk also works with RegEx and interprets text enclosed in slashes (/) as regular expressions.
<pre><code>awk '/keyword1/ &#x26;&#x26; /keyword2/' filepath.csv

Awk processes the file line by line. To be case insensitive, you can convert the line to lower text before searching your keywords:
<pre><code>awk '{lc=tolower($0)}; (lc ~ /keyword1/) &#x26;&#x26; (lc ~ /keyword2/)' filepath.csv
</code></pre>
Here, we take the current line $0 and create a variable lc containing the current line in lower case. Then we check for keywords in it.
In the screenshot below, I search in my CSV for a line with the keywords france AND google.

For example, to count how many lines match a keyword, combine it with the [single keyword search](#searching-in-a-big-csv-file-for-a-single-keyword).


```
grep -i "keyword" filepath.csv | wc -l

When searching for multiple keywords in a CSV file, you can search for one of the keywords or for all the keywords.
Searching for one of several keywords in a big CSV file
Grep with a RegEx is once again the perfect choice. In a RegEx, the symbol | means OR.
grep -i -E &quotkeyword1|keyword2&quot filepath.csv
And to search for whole keywords, we can add \b for each keyword.
grep -i -E &quot\bkeyword1\b|\bkeyword2\b&quot filepath.csv
Search CSV for multiple keywords
Searching for all the keywords in a big CSV file
To search for lines in your CSV file that have all the requested keywords, you can use another command: awk. Awk is another command tool to deal with text files. It has more advanced features.
Awk also works with RegEx and interprets text enclosed in slashes (/) as regular expressions.
awk &#39/keyword1/ &amp&amp /keyword2/&#39 filepath.csv
Awk processes the file line by line. To be case insensitive, you can convert the line to lower text before searching your keywords:
awk &#39{lc=tolower($0)}; (lc ~ /keyword1/) &amp&amp (lc ~ /keyword2/)&#39 filepath.csv
Here, we take the current line $0 and create a variable lc containing the current line in lower case. Then we check for keywords in it.
In the screenshot below, I search in my CSV for a line with the keywords france AND google.
Search CSV for all keywords
How to count the number of matching rows?
Several commands can be combined. An important command is wc for word count. It does a great job at counting words or lines in a text file.
Use the -l option to count lines in a CSV file or after another command.
For example, to count how many lines match a keyword, combine it with the single keyword search.
grep -i &quotkeyword&quot filepath.csv | wc -l
Count how many lines match a keyword


You have a very big CSV file, and you want to split it into several files of n lines. Smaller files let you open them with <a href="/csv-editor">CSV editors</a> without reaching their limits.

You have a very big CSV file, and you want to split it into several files of n lines. Smaller files let you open them with [CSV editors](/csv-editor) without reaching their limits.

If you are not afraid of using the terminal, macOS and Linux come with a simple utility to split files into parts: [**split**](https://man7.org/linux/man-pages/man1/split.1.html). [See full documentation on split man page.](https://man7.org/linux/man-pages/man1/split.1.html)

```
split [-l line_count] [-b byte_count] [-n chunk_count] [file [prefix]]
```

The command `split` breaks up files using:
- **lines** - useful for text-based files
- **bytes** - for binary files
- **number** - if you want to split a file into a specific number of parts.

[CSV is a format to store structured data using text files.](/learn/csv/csv-meaning) In a CSV file, each line is a data record. **To split a CSV file, we'll use `split` with the `lines` parameter.**

```
split -l 100000 filename.csv
```

![Basic split CSV file](/learn_images/csv/split-csv-file/basic-split-file.png#1392x350=.with-shadow.rounded-3.mb-4)

`Split` generates files with basic names beginning with **x**: `xaa`, `xab`, `xac`, etc. See the next section to split your CSV files and rename the generated files.

### Using split and renaming generated files

`Split` has two interesting parameters. The first is **-d** to use numeric suffixes (1, 2, 3, etc.) instead of letters. The second is the **prefix** parameter for the generated files. To define the **prefix**, just add a string after your CSV filename.

```
split -l 100000 -d filename.csv file_
```

![split CSV file with prefix and numeric suffixes](/learn_images/csv/split-csv-file/split-numeric-prefix.png#1182x350=.with-shadow.rounded-3.mb-4)

Then, loop on all files starting with `file_` and rename them to add `.csv`.

```
for i in $(find file_*); do mv $i "$i.csv"; done
```

### Adding CSV header to generated files

You have several generated files like: `file_00.csv`, `file_01.csv`, etc.

But the [CSV header line](/learn/csv/csv-headers) is on the first file (`file_00.csv`) and all other files don't have a CSV header line.

To copy the file_00.csv first line on all other files, run the following command:

```
for i in $(find . -type f -name "file_*.csv" -not -name "file_00.csv");
    do echo -e "$(head -1 file_00.csv)\n$(cat $i)" > $i;
done
```

What it does is simple:

**Step1**

Loop on all file that begin with **file_** but are not **file_00.csv**:

`find . -type f -name "file_*.csv" -not -name "file_00.csv"`


**Step2**

For each file in the loop, copy the first line of `file_00.csv` to it. There is no easy way to prepend a line to a file using the command line. We just use `echo` with the first line from file_00.csv and the file content from the current file `cat $i`.


### To Sum up the whole process

Step 1: Split the CSV file into parts of 100000 lines and prefix the generated files with "file_".

```
split -l 100000 -d filename.csv file_
```

Step 2: Add `.csv` to all generated files.

```
for i in $(find file_*); do mv $i "$i.csv"; done
```

Step 3: Copy header from first generated file at the beginning of the other files.
```
for i in $(find . -type f -name "file_*.csv" -not -name "file_00.csv");
    do echo -e "$(head -1 file_00.csv)\n$(cat $i)" > $i;
done
```

Spreadsheet and database both store sets of data. However, each one has advantages and disadvantages and is suited to specific use cases.
A spreadsheet represents a digital worksheet and was invented for accounting tasks. In a spreadsheet, data is stored in a flat structure consisting of rows and columns, also known as tabular format. Spreadsheets are simple to use and require no technical knowledge. Because a spreadsheet is flexible and doesn't have a data schema, any value can be entered in any cell. The drawback of this flexibility is the lack of data schema. Spreadsheets cannot be used safely as a source of data for other applications as they cannot provide a strict structure.
Finally, spreadsheets are designed to handle a limited volume of data.
In databases, data is stored in tables, which have a defined structure. This data structure describes for each table, the attributes and data types expected. For example, attributes can be text, date, text, or relationship to another table. This data structure adds constraints and triggers errors directly when inserting a new record in the database. Thanks to this strict structure, other applications can rely on the data provided by a database.
Unlike spreadsheets, databases are better for storing large amounts of data and when several users or applications access the data simultaneously.

[CSV headers are optional](/learn/csv/csv-headers). But if you need to import your CSV into another software or [clean it with a CSV editor](/csv-editor), you better have them.

Just `copy - paste` the columns from the first sheet or write them directly as the first line in the new sheet.

![Paste columns in the new sheet](/learn_images/excel/export-selection-csv/paste-headers.png#1732x1294)

## Step 3: Export sheet to CSV

The last step is to export the new Excel sheet to a CSV file. Once you are on the new sheet, select `Save As` in the `File` menu.

> **Important**: Set the active sheet to the sheet to export!

![File -> Save As](/learn_images/excel/export-selection-csv/save-as-to-export-csv.png#1374x1076)

Then change the `File format` to `CSV UTF-8 (Comma-delimited) (.csv)`. And click `Save`.

![Save As with CSV format](/learn_images/excel/export-selection-csv/select-csv-as-export-format.png#1780x1294)

A warning message will pop up with the message "This workbook cannot be saved in the selected file format because it contains multiple sheets.".

Bypass the warning message by clicking on `OK`. Microsoft Excel tells you that it can't export all sheets to a single CSV. Only your active sheet will be exported to a CSV file. This is what we want.

![Confirm with OK](/learn_images/excel/export-selection-csv/confirm-to-export-active-sheet.png#1512x1076)


## Edit it with a CSV Editor

If you need to further clean your CSV data, use a [CSV Editor](/csv-editor) such as [Datablist](/csv-editor).

Datablist provides advanced tools to [deduplicate data](/features/duplicates-remover), [consolidate several CSV files](/features/combine-csv-files), or [clean your data](/how-to/clean-web-scraping-data-online).







Export Microsoft Excel selection into a CSV file

Exporting a sheet from Microsoft Excel to a CSV file is straightforward. But how to export selected cells to a CSV file?
The short answer is you can&amp#39;t export selected cells in CSV quickly. Exporting a selection to a CSV file or another Excel file is not directly possible. Here is an alternative solution: copy the data to another sheet and export the sheet to a CSV file. 
Step 1: Copy-Paste selected cells
Select the cells you want to export. And copy the data to your clipboard (ctrl+c or Menu Edit =&ampgt; Copy)
File -&ampgt; Export To -&ampgt; CSV
Export only visible cells (without hidden columns)
If you have hidden columns, Excel will add their content to your clipboard. This is not what we want. We want to export only our selected and visible cells.
To prevent hidden columns to be copied, open the Go to Special menu in Find &ampamp; Select.
Find &ampamp; Select -&ampgt; Go to Special
And select Visible cells only. It will tell Microsoft Excel we only want to copy the visible cells.
Go to special -&ampgt; Visible cells only
Step 2: Create a new sheet and paste your data
Then, create a new sheet and paste your data (ctrl + v or Menu Edit =&ampgt; Paste)
Paste data in a new sheet

File -&ampgt; Save As
Then change the File format to CSV UTF-8 (Comma-delimited) (.csv). And click Save.
Save As with CSV format
A warning message will pop up with the message &ampquot;This workbook cannot be saved in the selected file format because it contains multiple sheets.&ampquot;.
Bypass the warning message by clicking on OK. Microsoft Excel tells you that it can&amp#39;t export all sheets to a single CSV. Only your active sheet will be exported to a CSV file. This is what we want.
Confirm with OK
Edit it with a CSV Editor
If you need to further clean your CSV data, use a CSV Editor such as Datablist.
Datablist provides advanced tools to deduplicate data, consolidate several CSV files, or clean your data.

When it comes to storing data online, spreadsheets and databases are two possible options. Understanding the differences between them is crucial to find the best tool for your task.
Spreadsheets (Excel and Google Sheets) are easy to use and inexpensive. They are the go-to solution when it comes to simple analytics and data manipulation. For example, spreadsheet tools offer analytics features to display charts or create pivot tables.
Databases are designed to handle larger datasets and structured data. They offer built-in data constraints to force field format or to avoid duplicate information. Databases have powerful query languages to search and filter their data. These features are powerful but add complexity compared to spreadsheets. As a result, databases have a steep learning curve.
If you need to connect to your data programmatically, databases are the go-to solution. Thanks to its data structure, a database ensure the data is valid before saving it.
If you need to store less than 1 million records and don't need to connect your data to an application, spreadsheets do the job.

If you’ve got a long list of email addresses, manually sorting out business from personal emails can feel like finding a needle in a haystack.
But here’s the good news: Datablist’s <a href="/enrichments/free-email-validator-bulk">Free Email Validator</a> can do this for you in bulk, with just a few clicks.
It’s a simple, fast way to identify whether an email is linked to a business domain or a personal email provider. For free!
We’ve all seen personal email addresses like <code>john.doe@gmail.com</code> or <code>sarah@yahoo.com</code>. These are free, generic email providers, and people use them for everyday communication. Business emails, on the other hand, usually have a custom domain like <code>info@companyname.com</code> or <code>jane@startup.com</code>.
If you’re sending marketing campaigns or segmenting contacts, this distinction can help you tailor your approach. For example, business emails may require a more formal message than personal ones.

Lead Deduplication, or <a href="/features/duplicates-remover">lead deduping</a>, is the process of finding, and merging duplicate records to have a clean list of unique entries.
A lead represents a person or a company. A duplicate lead is when there are multiple records for the same person or company.
Duplicate leads appear when you have several lead sources that pour into a single lead list. Examples of lead sources are lead magnets, webinars, newsletters, or manual entries.
👉 Check our <a href="/how-to/merge-duplicate-leads-without-losing-data">guide to remove duplicate leads from your list.</a>
The main steps for lead deduplication typically include:
<ol>
<li>
Data Collection: Gather the leads from various sources, such as online forms, CRM systems, marketing automation platforms, and manual entry. The best format to extract data from all sources is the <a href="/learn/csv/csv-meaning">CSV format</a>. Use our <a href="/csv-editor">CSV Editor</a> to import and consolidate all your files.
</li>
<li>
Data Cleansing: Cleanse and standardize the leads by removing any irrelevant or incomplete entries, correcting formatting issues, and normalizing data fields to ensure consistency.
</li>
<li>
Define Duplicate Scoring Algorithm: This involves setting what constitutes a duplicate. For lead deduplication, you want to define your matching criteria on unique identifiers: email address, phone number, or contact name. For company leads the best identifier is the company website. Then, you can select how to compare values between leads. Do you want an exact match on names, or use fuzzy matching to match duplicate leads with slight changes.
</li>
<li>
Duplicate Identification: Run the deduplication algorithm on your leads. Duplicate groups are created with leads having a high similarity score.
</li>
<li>
Data Consolidation: Merge or update the duplicate records to create a single, consolidated, and accurate lead entry. This may involve merging contact details, activity history, and any associated information. <a href="/features/combine-csv-files">Data Consolidation</a> can be done automatically using rules or manually for conflicting leads.

Then, you can select how to compare values between leads. Do you want an exact match on names, or use fuzzy matching to match duplicate leads with slight changes. 

1. Duplicate Identification: Run the deduplication algorithm on your leads. Duplicate groups are created with leads having a high similarity score.

1. Data Consolidation: Merge or update the duplicate records to create a single, consolidated, and accurate lead entry. This may involve merging contact details, activity history, and any associated information. [Data Consolidation](/features/combine-csv-files) can be done automatically using rules or manually for conflicting leads.

When to dedupe leads?

Lead Deduplication, or lead deduping, is the process of finding, and merging duplicate records to have a clean list of unique entries.
A lead represents a person or a company. A duplicate lead is when there are multiple records for the same person or company.
Duplicate leads appear when you have several lead sources that pour into a single lead list. Examples of lead sources are lead magnets, webinars, newsletters, or manual entries.
👉 Check our guide to remove duplicate leads from your list.
The main steps for lead deduplication typically include:
Data Collection: Gather the leads from various sources, such as online forms, CRM systems, marketing automation platforms, and manual entry. The best format to extract data from all sources is the CSV format. Use our CSV Editor to import and consolidate all your files.

Data Cleansing: Cleanse and standardize the leads by removing any irrelevant or incomplete entries, correcting formatting issues, and normalizing data fields to ensure consistency.

Ever wondered which email providers are behind the email addresses in your contact list? Knowing this information can be incredibly useful, whether you’re segmenting business emails from personal ones or checking the reliability of email domains. One effective way to uncover this is by looking at the MX (Mail Exchange) records associated with the email domains.
The good news? Datablist’s <a href="/enrichments/free-email-validator-bulk">Free Email Validator</a> enrichment can help you do this in just a few steps!
<h2 id="user-content-what-are-mx-records"><a href="#what-are-mx-records" aria-hidden="true" tabindex="-1"></a>What Are MX Records?</h2>
MX records are part of a domain's DNS (Domain Name System) settings. They tell email servers where to deliver emails sent to that domain. By querying the MX records, you can identify which email service (provider) is handling the email for a particular domain.
For example, when you send an email to <code>someone@gmail.com</code>, the MX records will show that <code>Google</code>’s servers manage the email. Similarly, business domains have their own mail servers or use third-party email providers like Outlook or G Suite.

An Impressum is a legally mandated statement in German-speaking countries, required in publications like books, newspapers, websites, and business correspondence. It must include details about the ownership and authorship of the document.
Most websites in German-speaking countries have an Impressum page with their contact information.
Scraping this data is perfect for lead generation. Impressum pages contain valuable data such as:
<ul>
<li>Founder/CEO Name</li>
<li>Job title</li>
<li>Phone Number</li>
<li>Email Address</li>
<li>Postal Address</li>
</ul>
The information is available but not in a structured format. Until now, it was hard to extract automatically that information. But with AI, I'll show you how to extract those contact information in a structured format.

First, import a CSV/Excel file with a list of websites you want to scrape. Datablist is a lead management tool with superpowers. One of them is the Datablist AI Agent. Our AI Agent understands text and can scrape website to find relevant data.
To import your CSV file, create an empty collection and click import. Or click on the "Start with a CSV/Excel file" button from the home screen.
<img src="/learn_images/scraping/scrape-impressum/create-collection-from-file.png#2270x1361" alt="Import CSV File">

<h2 id="user-content-step-2-write-a-prompt-that-works"><a href="#step-2-write-a-prompt-that-works" aria-hidden="true" tabindex="-1"></a>Step 2: Write a prompt that works</h2>
Now, we will ask an AI Agent to visit each website, find the Impressum page link, and then read the Impressum page to extract contact information.
Click on the "Enrich" menu and select "AI Agent".
<img src="/learn_images/scraping/scrape-impressum/ai-agent-enrichment-blur.png#2297x1229" alt="Open AI Agent">
We must write a prompt with the website URL to visit, and the data we want to extract. And we can add some tips to find the Impressum page.
Here is my prompt:
<pre><code>Visit {{WEBSITE}} and scrape the impressum page to extract the following information: 
- Founder name
- Job Title
- Email Address
- Phone Number
The Impressum page is usually on the URL /impressum

You can ask for more (or less) data points. The website URL is defined as a placeholder. And Datablist will run a personalized prompt for each line.
To use a variable for the website, enter 2 brackets characters and select the Website property from your collection.

<li>Founder Name - Description: The name of the founder. Empty if not found.</li>
<li>Job Title - Description: The job title of the founder, when available.</li>
<li>Email Address - Description: Email address found on the impressum page.</li>

## Step 1: Import your list of websites

First, import a CSV/Excel file with a list of websites you want to scrape. Datablist is a lead management tool with superpowers. One of them is the Datablist AI Agent. Our AI Agent understands text and can scrape website to find relevant data.

<aside class="text-center mb-5">
 <div class="mb-2">
 <a href="https://app.datablist.com/" className="btn btn-primary btn-large" target="_blank">
 Open Datablist
 </a>
 </div>
</aside>

To import your CSV file, create an empty collection and click import. Or click on the "Start with a CSV/Excel file" button from the home screen.

![Import CSV File](/learn_images/scraping/scrape-impressum/create-collection-from-file.png#2270x1361)

This is my file imported. It contains two columns: the name of the company, and its website.

![List of German websites to scrape](/learn_images/scraping/scrape-impressum/list-websites-blur.png#2423x1327)


## Step 2: Write a prompt that works

Now, we will ask an AI Agent to visit each website, find the Impressum page link, and then read the Impressum page to extract contact information.

Click on the "Enrich" menu and select "AI Agent".

![Open AI Agent](/learn_images/scraping/scrape-impressum/ai-agent-enrichment-blur.png#2297x1229)

We must write a prompt with the website URL to visit, and the data we want to extract. And we can add some tips to find the Impressum page.

Here is my prompt:

```
Visit {{WEBSITE}} and scrape the impressum page to extract the following information: 
- Founder name
- Job Title
- Email Address
- Phone Number
The Impressum page is usually on the URL /impressum
```

You can ask for more (or less) data points. The website URL is defined as a placeholder. And Datablist will run a personalized prompt for each line.

**To use a variable for the website, enter 2 brackets characters and select the Website property from your collection.**

![Write a prompt](/learn_images/scraping/scrape-impressum/write-prompt.png#1526x930)

## Step 3: Configure expected outputs

After the prompt, we need to configure the expected outputs. The Agent uses the output's name and description along with the prompt to understand the mission.

Here, we have:

- **Founder Name** - Description: The name of the founder. Empty if not found.
- **Job Title** - Description: The job title of the founder, when available.
- **Email Address** - Description: Email address found on the impressum page.
- **Phone Number** - Description: The company phone number.

![Expected outputs](/learn_images/scraping/scrape-impressum/expected-outputs.png#1758x1248)


## Step 4: Add outputs to the collection

Click "Continue to outputs configuration". The expected outputs configured in the previous step appear here.

Select "+" to add a new property (=column) to your collection for each output.

![Add properties](/learn_images/scraping/scrape-impressum/add-properties.png#2292x1380)

You can also create a property to see the error message when the agent is not able to perform the task.

## Step 5: Run the enrichment

The last step, click on "Instant run" to run the agent.

![Scraping results](/learn_images/scraping/scrape-impressum/results-blur.png#2537x1398)

The "Error Msg" property shows a text when the agent is not able to reach the website or if no Impressum page is found.

Automatically extract contact information on the Impressum page

An Impressum is a legally mandated statement in German-speaking countries, required in publications like books, newspapers, websites, and business correspondence. It must include details about the ownership and authorship of the document. 
Most websites in German-speaking countries have an Impressum page with their contact information.
Scraping this data is perfect for lead generation. Impressum pages contain valuable data such as:
Founder/CEO Name
Job title
Phone Number
Email Address
Postal Address

The information is available but not in a structured format. Until now, it was hard to extract automatically that information. But with AI, I&amp#39;ll show you how to extract those contact information in a structured format.

The Double Metaphone algorithm is a phonetic algorithm that is used to convert words into a phonetic code. The code can then be used to compare words and names that sound similar, even if they are spelled differently. The Double Metaphone algorithm is an improvement over the original Metaphone algorithm and was created by Lawrence Philips in 2000.
<h2 id="user-content-how-does-the-double-metaphone-algorithm-work"><a href="#how-does-the-double-metaphone-algorithm-work" aria-hidden="true" tabindex="-1"></a>How does the Double Metaphone algorithm work?</h2>
The Double Metaphone algorithm works by first removing all non-alphabetic characters from the word. Next, all vowels are removed, unless the word begins with a vowel. The remaining consonants are then processed according to a set of rules. These rules take into account the pronunciation of English consonants, as well as the way that consonants are often combined in English words.
The Double Metaphone algorithm generates two phonetic codes for each word. The first code is called the primary code and is used for most comparisons. The second code is called the secondary code and is used for comparisons where the primary code is not unique.
For example, the word "Smith" would be converted to the primary code "SMT" and the secondary code "XMT" by the Double Metaphone algorithm. This is because the "th" sound can be pronounced as either "S" or "X" in English, so both codes are generated.

<li>
Language Agnostic: The Double Metaphone Algorithm works well with a multitude of languages, making it suitable for applications requiring cross-lingual compatibility.
</li>
<li>
Accurate Phonetic Encoding: It generates phonetic encodings that reflect the way words are spoken, enhancing the accuracy of searches and matches in databases and applications. The Double Metaphone algorithm is more accurate than Soundex and Metaphone at matching words that sound similar. This is because the Double Metaphone algorithm takes into account more of the pronunciation of English consonants.
</li>
<li>
Variation Handling: By providing primary and secondary codes, the algorithm accommodates the various ways a word might be pronounced, increasing the chances of capturing relevant results.
</li>
<li>
Improved Spell Correction: The Double Metaphone Algorithm aids in spell correction by identifying words that sound similar but are spelled differently.

The Jaro-Winkler Distance is a similarity measure that quantifies the difference between two strings, often used in the context of record linkage, data deduplication, and string matching. It's an extension of the Jaro Distance metric and takes into account prefixes of matching characters.
<h2 id="user-content-how-does-the-jaro-winkler-distance-work"><a href="#how-does-the-jaro-winkler-distance-work" aria-hidden="true" tabindex="-1"></a>How does the Jaro-Winkler Distance work?</h2>
The Jaro-Winkler Distance computes a value between 0 and 1, where 0 indicates no similarity and 1 represents identical strings. It considers the number of matching characters, the number of transpositions (swapped characters), and a scaling factor for common prefix matches. The scaling factor in Jaro-Winkler gives higher weight to prefix similarities, making it especially effective for cases where slight misspellings or prefixes are common.
<h2 id="user-content-why-is-the-jaro-winkler-distance-important"><a href="#why-is-the-jaro-winkler-distance-important" aria-hidden="true" tabindex="-1"></a>Why is the Jaro-Winkler Distance important?</h2>
Jaro-Winkler is particularly useful when dealing with strings that might have minor discrepancies due to typos, abbreviations, or phonetic variations. Its emphasis on matching prefixes makes it robust against cases where two strings are similar but not identical. This makes it valuable for applications like deduplication, spell correction, and name matching.
<h2 id="user-content-how-is-the-jaro-winkler-distance-calculated"><a href="#how-is-the-jaro-winkler-distance-calculated" aria-hidden="true" tabindex="-1"></a>How is the Jaro-Winkler Distance calculated?</h2>
The calculation involves three main steps: computing the Jaro Distance (a value between 0 and 1), calculating the common prefix length, and applying the Jaro-Winkler formula. The formula takes into account the Jaro Distance, and the prefix scaling factor (usually 0.1 or 0.25), and adjusts the similarity score accordingly.
<h2 id="user-content-what-are-the-limitations-of-the-jaro-winkler-distance"><a href="#what-are-the-limitations-of-the-jaro-winkler-distance" aria-hidden="true" tabindex="-1"></a>What are the limitations of the Jaro-Winkler Distance?</h2>
While effective, the Jaro-Winkler Distance may not be ideal for all scenarios. It's sensitive to the choice of scaling factor, which needs to be tuned based on the specific dataset and application. Additionally, it might not capture more complex semantic differences between strings.

The Jaro-Winkler distance is suited for <a href="/learn/data-cleaning/fuzzy-matching">Fuzzy Matching</a> and data deduplication. This algorithm can be used to compute similarity in names, addresses, or any text fields. Using a threshold value, records with a similarity distance above the threshold are considered as duplicate records.

The Jaro-Winkler Distance is a similarity measure that quantifies the difference between two strings, often used in the context of record linkage, data deduplication, and string matching. It's an extension of the Jaro Distance metric and takes into account prefixes of matching characters.

## How does the Jaro-Winkler Distance work?

The Jaro-Winkler Distance computes a value between 0 and 1, where 0 indicates no similarity and 1 represents identical strings. It considers the number of matching characters, the number of transpositions (swapped characters), and a scaling factor for common prefix matches. The scaling factor in Jaro-Winkler gives higher weight to prefix similarities, making it especially effective for cases where slight misspellings or prefixes are common.

## Why is the Jaro-Winkler Distance important?

Jaro-Winkler is particularly useful when dealing with strings that might have minor discrepancies due to typos, abbreviations, or phonetic variations. Its emphasis on matching prefixes makes it robust against cases where two strings are similar but not identical. This makes it valuable for applications like deduplication, spell correction, and name matching.

## How is the Jaro-Winkler Distance calculated?

The calculation involves three main steps: computing the Jaro Distance (a value between 0 and 1), calculating the common prefix length, and applying the Jaro-Winkler formula. The formula takes into account the Jaro Distance, and the prefix scaling factor (usually 0.1 or 0.25), and adjusts the similarity score accordingly.

## What are the limitations of the Jaro-Winkler Distance?

While effective, the Jaro-Winkler Distance may not be ideal for all scenarios. It's sensitive to the choice of scaling factor, which needs to be tuned based on the specific dataset and application. Additionally, it might not capture more complex semantic differences between strings.

## How to use Jaro-Winkler Distance to find duplicate records?

The Jaro-Winkler distance is suited for [Fuzzy Matching](/learn/data-cleaning/fuzzy-matching) and data deduplication. This algorithm can be used to compute similarity in names, addresses, or any text fields. Using a threshold value, records with a similarity distance above the threshold are considered as duplicate records.

Levenshtein Distance, often referred to as edit distance, is a fundamental concept in string comparison and analysis. It quantifies the difference or similarity between two strings by calculating the minimum number of single-character edits required to transform one string into another. These edits can be in the form of insertions, deletions, or substitutions of individual characters.

Imagine comparing the words "kitten" and "sitting." The Levenshtein Distance between these words is 3, as three operations are needed to change "kitten" into "sitting": substitute 'k' with 's,' insert 'i' after 'k,' and substitute 'e' with 'g.' This distance value provides a numerical measure of the similarity between the two words, considering variations like typos, misspellings, and other minor changes.

Fuzzy matching is a sophisticated data comparison technique used to identify similarities between strings or records, even when they're not an exact match. Unlike traditional exact matching, which requires two strings to be identical to consider them a match, fuzzy matching takes into account variations, errors, and discrepancies in the data. This makes it highly effective in scenarios where data might be slightly different due to typos, abbreviations, misspellings, or other inconsistencies.
