Limitations
Matches only what you tell it to match on — it won't detect duplicates that use different spelling or formatting for the same value unless you clean that first.
FAQ
Which row does it keep when it finds a duplicate?
You choose — the tool lets you keep either the first or the last occurrence of a matching row.
Can I match on more than one column?
Yes — you can select a single column, several columns together, or every column for an exact-row match.
Will this change my original file?
No — it reads your file and produces a new one; your original upload is never modified in place.
