Multi-Select & Mass Merge

When you trust your scenario's master rules, you don't have to merge group by group — Data Cleanser can merge many groups in one go.

Multi-select merge

Tick checkboxes in the duplicate queue, then click Merge N selected. Each group merges using its current master settings. Cross-object groups can't be multi-selected — they use the conversion flow instead.

Mass merge all groups

Mass merge all groups merges every detected group for the current object using the active scenario's master rules. Click Schedule merge to queue the job — it runs in the background.

"This merges every detected duplicate group for [object] using the active scenario's master rule. Each merge can be rolled back within about 15 days in Review → Rollback when you have the Pro + Rollback license. Your request will be scheduled — check back later to see results."

Partial failures never stop the batch — a group that can't merge is logged to Warnings and the run continues.
