About the TSV to CSV Converter

This tool converts TSV to CSV in both directions. Values containing commas, quotes or line breaks are quoted and escaped to the CSV standard, so a tab-separated export becomes a file that importers actually accept.

Convert TSV to CSV when something upstream produced tab-separated text but the tool you need to feed only documents CSV. Database exports, analytics downloads and anything copied out of a spreadsheet commonly arrive tab-separated.

The important part is escaping. Once tabs become commas, any value that already contained a comma would break the column layout — so values containing commas, quotes or line breaks are wrapped in quotes and internal quotes are doubled, exactly as the CSV standard requires.

Conversion works both ways from this page, so it doubles as a TSV exporter when a system wants tab-separated input instead. Everything runs in your browser.

How to use the TSV to CSV Converter

  1. Paste or upload your data. Provide the tab-separated text, or CSV if you are going the other way.
  2. Choose the direction. Convert TSV to CSV, or CSV to TSV.
  3. Convert. Run the conversion, applying quoting and escaping where needed.
  4. Copy or download. Copy the output or save it as a file.

Frequently asked questions

Does it convert in both directions?

Yes. TSV to CSV and CSV to TSV are both available from this page.

How are commas inside values handled?

Values containing commas, quotes or line breaks are wrapped in quotes and internal quotes are doubled, per the CSV standard.

Why not just replace tabs with commas myself?

Because any value already containing a comma would break the columns. Proper quoting is what makes the file importable.

Is the first row treated as a header?

It is passed through unchanged, so a header row stays a header row in the output.

Is anything uploaded?

No. The conversion runs entirely in your browser.
