Remove duplicates from Excel
Exact duplicate rows and repeated customer records are the fastest way to break a CRM import. Upload your Excel file, see how many duplicates exist, and remove them after review.

Remove duplicates nowHow duplicate removal works
- We scan for fully identical rows across all columns.
- Duplicate record detection flags repeated values in key columns like email.
- You see counts before any rows are removed.
- Download a deduplicated file with a summary of changes.
Exact duplicates vs duplicate records
- Treating rows as duplicates when only the email matches — sometimes intentional.
- Removing duplicates before fixing whitespace — "John" and " John" look different.
- Deduping without a backup of the original export.
- Ignoring near-duplicate names that should be merged manually.
