Common questions
Excel Duplicate Finder FAQ
Are my spreadsheet files uploaded?
No. PapaTool reads, transforms and exports your file inside this browser tab. File contents are never sent to PapaTool servers.
How are duplicate rows matched?
Values are normalized into stable keys. Choose all columns for exact rows or selected key columns for business identifiers.
