Find and remove duplicate rows in CSV or Excel files — match on any columns, exact or fuzzy, with a full preview before anything is removed.
Load the file, choose which columns define a duplicate (all of them, or keys like email/ID), pick exact or normalized matching, review the groups, and download the deduplicated file. Nothing is removed without you seeing it first.
It lowercases values, trims and collapses whitespace, and strips punctuation before comparing — so "Acme Co." and "acme co" match. This catches the near-duplicates that exact comparison misses.
