Remove duplicate rows from your Excel file — free.
Upload a spreadsheet and get a clean copy back with the repeated rows taken out. When two rows are identical, we keep the first one and drop the later copies — everything else stays exactly where it was, and your original workbook is never changed.
What counts as a duplicate
A row is a duplicate when every one of its cells matches an earlier row exactly — same values, in the same columns. The first time a row appears it’s kept; any later row that repeats it is removed. Rows that differ in even a single cell are always left alone.
Your header row is safe
We treat the top row as your column headings and never remove it, even if two data rows below happen to repeat those labels. Only the data underneath is checked for duplicates.
How it works
The page runs the same de-duplication your AI agent would call through our tools. It reads your file in
memory and never stores it — your original .xlsx is untouched; you download a new copy with
the duplicates removed, so nothing is ever lost.
Want this inside your AI agent, on your own machine, with no upload at all? Install xlsx-for-ai and ask Claude or Cursor to “remove the duplicate rows from this workbook.”
