How it works
Upload an Excel file and the tool compares every data row (everything after the header) against every other row. The first occurrence of each unique row is kept; any exact repeat that comes after it is dropped from the result.
Remove Duplicate Rows
Find and remove exact duplicate rows from a spreadsheet — no sign-up, no upload, no file size limit.

The first row is treated as a header and always kept. A row counts as a duplicate only when every column matches another row exactly — the first occurrence is kept.
Your files never leave your device. Everything runs locally in your browser — nothing is uploaded to a server, so there's no file size limit, no subscription, and no one but you ever sees what's in your file.
Frequently asked questions
What counts as a duplicate?+
A row where every column exactly matches another row (including the same capitalization and spacing). If two rows differ in even one cell — say, a slightly different date format — they're treated as different rows.
Which copy of a duplicate gets kept?+
The first one, in top-to-bottom order. Every row after it that matches is removed.
Can I remove duplicates based on just one or two columns, ignoring the rest?+
Not currently — this tool compares the entire row. For column-specific deduplication (e.g. "unique by email address only"), you'd need a spreadsheet formula or a more specialized tool.
Is my file uploaded anywhere?+
No. This tool runs entirely in your browser using JavaScript — your spreadsheet is read, cleaned, and downloaded without ever being sent to a server.
Keep a backup of your original file. This tool processes everything locally in your browser, and we've tested it carefully — but no conversion tool handles every PDF perfectly. Always keep your original file and double-check important results before relying on them.
