Remove Duplicate Rows from CSV Online
Open a CSV to preview exact duplicate rows before removing any of them.
Files are kept for up to 30 minutes after your last activity. Unsaved edits cannot be recovered after a server restart.
The current duplicate check compares complete rows. Preview the rows that would be removed, apply once, or go back without changing the file.
Questions about this tool
Can I choose columns for duplicate matching?
Not yet. This tool compares complete rows; it does not deduplicate by a chosen subset of columns.
