TSV to CSV Converter

Paste a tab-separated file and download a clean comma-separated CSV.

Convert TSV (tab-separated values) to CSV in one click. Quoting is reapplied so any value containing a comma, quote, or newline is wrapped correctly. Header row is preserved.

How it works

  1. Paste your TSV into the editor (delimiter is preset to Tab).
  2. Confirm the output delimiter (preset to Comma).
  3. Unlock the result and download the .csv file.

Use cases

  • Convert a tab-separated export from a database tool into a CSV.
  • Turn a spreadsheet pasted as TSV into a CSV for a CRM import.
  • Re-encode a TSV log file as CSV for a data tool that expects commas.
  • Move data out of a tab-aware tool and into a comma-only importer.

Frequently asked questions

What if my values contain commas?

Handled automatically. The writer wraps any value containing a comma, quote, or newline in quotes, so the CSV reads correctly in every standard parser.

Is the header preserved?

Yes. When 'First row is a header' is ticked the first row is kept exactly as-is at the top.

Can I switch to a different output delimiter?

Yes. Change the output delimiter to semicolon, pipe, or a custom character if you don't want commas.

Is there a size limit?

Up to 2 MB of input per job, comfortably tens of thousands of rows.

How long is the result kept?

The converted .csv is auto-deleted after 7 days. Re-download is available during that window via the secure link.
