CSV to TSV Converter (and TSV to CSV)
Free, no sign-up, works in your browser. Switch delimited data between comma-separated (CSV) and tab-separated (TSV) in one step. Quoted values, commas inside values and line breaks are handled correctly, so no column shifts.
Values that contain tabs, quotes or line breaks are quoted, so nothing shifts into the wrong column. Tip: TSV pastes straight into a spreadsheet.
Your data stays on your device.

Frequently asked questions
- What's the difference between CSV and TSV?
- Both store a table as text. CSV separates values with commas (or semicolons in some countries); TSV uses tab characters, which rarely appear inside data.
- Will values that contain commas break?
- No. The tool reads quoted values properly and quotes any value that needs it in the output.
- Can it convert semicolon or pipe-separated files?
- Yes. Semicolons, pipes and tabs are detected automatically, or you can pick the separator yourself.
- Is my data uploaded?
- No. Everything happens on your device.
- Is the CSV to TSV Converter free?
- Yes. It's free to use, with no sign-up and nothing to install.
