About this page
Excel’s remove duplicates dialog is fine for one-off work, but browser tools help when you cannot install Office or need a quick paste-and-clean flow.
Full-row mode removes lines that match across every column. Switch to first-column mode in the tool to dedupe by a single key such as email.
How to use
- Export your sheet as CSV or XLSX, or paste copied cells.
- Upload or load the data, confirm Remove duplicates is on.
- Click Clean data, review the preview, then download CSV or XLSX.
FAQ
- Can I dedupe by one column only?
- Yes. Choose “First column only” under duplicate mode to keep the first row per value in column A.
- Is my data uploaded?
- No. Files and pasted text are processed locally in your browser.
- Is this tool free?
- Yes. No registration is required.
