Clean CSV & Excel

Drop a spreadsheet

CSV · Excel · TSV · stays on your device

Convert a tab-separated values (TSV) file to a comma-separated CSV, right in your browser. The delimiter is detected automatically, and values that contain commas are quoted correctly so the output stays valid. Nothing is uploaded.

Handy when a tool exports tab-delimited data but the next tool only accepts CSV.

How to convert tsv to csv

  1. Drop your TSV or .txt file.
  2. Leave "Save as CSV" selected.
  3. Download the CSV.

Frequently asked questions

Do I need to tell it the file is tab-separated?

No — the delimiter (tab, comma or semicolon) is detected automatically from the first row.

What about values that contain commas?

They are wrapped in quotes in the CSV output, so the columns stay intact.

Is my file uploaded?

No. Conversion runs in your browser.
