Keep the first exact match

Remove duplicate CSV rows

Remove repeated rows from a small campaign or listing export in your browser. See the before-and-after counts, inspect the cleaned CSV, and download it.

Example: two identical newsletter rows become one. Newsletter and newsletter remain separate because case and spaces are meaningful.

What this tool cannot establish

  • Matches complete rows only, not selected columns or fuzzy identities. Limited to 100 data rows, 30 columns and 12 KB; a header is required.
  • Quoted commas and line breaks are supported. Formula-like cells receive an apostrophe for safer spreadsheet opening; output uses CRLF line endings.
