Multi-value deduplication finds records that share one value inside a cell that contains several values.

Examples include several emails, website URLs, tags, identifiers, or skills in one property.

john@example.com;sales@example.com
sales@example.com

The complete cells differ, but both contain sales@example.com.

How multi-value matching works in Datablist

Datablist's Multiple Values option splits a text-based property at semicolons, trims spaces around each part, and applies the selected Exact or Smart processor to every part. The property matches when at least one processed value matches.

Commas, pipes, and line breaks are not separators for this setting. Convert them to semicolons before running the check.

Multiple Values is an advanced matching option available on paid plans. It changes comparison only and does not rewrite the stored cells.

📌 Matching and merging are separate

If the matching property contains different complete cell values, it appears as a normal merge conflict. Choose whether to combine the cells, keep the selected record's value, or apply a field rule.

Use Smart with the Email processor for cells containing several emails. Use a processor that matches the stored data for URLs or other identifiers.

Follow the measured 200-row multi-value deduplication guide for the exact settings, screenshots, sample input, and exported groups. See the Multiple Values product reference for limitations.
