About this tool
Scan a spreadsheet for rows that are exact duplicates of an earlier row and remove them, keeping the first occurrence — useful for cleaning up exported or combined data before analysis.
How is a duplicate defined?
A row counts as a duplicate only if every cell matches an earlier row exactly.
Will my header row be removed?
No, tick "First row is a header" (checked by default) to always keep it.
Is my spreadsheet uploaded anywhere?
No, the cleanup happens entirely in your browser.
