TSV to CSV Converter

Convert tab-separated values (TSV) to comma-separated values (CSV) - correctly quotes any field that itself contains a comma.

Paste or upload TSV data below - this tool re-delimits it as proper, correctly-quoted CSV.

A field that happens to contain a comma is automatically quoted in the CSV output, since an un-quoted comma would otherwise be misread as a new column.

Why Not Just Replace Tabs with Commas?

A naive find-and-replace of tabs with commas silently corrupts any field that already contains a comma, since CSV readers would then misinterpret it as an extra column boundary. This tool parses the TSV properly and re-serializes it as correctly-quoted CSV.

How to Use It

  1. Paste or upload TSV data.
  2. Click Convert.
  3. Copy or download the resulting CSV.

Limitations

This assumes standard tab-delimited input without CSV-style quoting inside the TSV itself (which is unusual for real TSV files) - if your source data already uses quoted fields, verify the result carefully.
