About this tool

Tab-separated values paste straight into a spreadsheet as columns, and they avoid the constant escaping that commas force on text containing prose, prices, or addresses. This tool re-separates a CSV file with tabs.

The file is parsed properly rather than having its commas replaced, so quoted fields containing commas survive intact instead of being split apart.

Supported formats and limits

Input
.csv
Output
.tsv (text/tab-separated-values)
Output name
The original name with the new extension, for example data.csv becomes data.tsv.

In your browser. The file is not uploaded.

How to use it

  1. Choose a .csv file, or switch to Paste text and paste the rows directly.
  2. Select Convert, then download the .tsv file.

Limitations

  • A value that itself contains a tab has to be quoted in the output, which some simple TSV readers do not expect.
  • This tool expects comma separators. A semicolon-separated export will come through as a single column.
  • Values stay as text; no type conversion happens in either direction.
  • The file is read as UTF-8.

Frequently asked questions

Is my file uploaded?
No. The conversion runs entirely in your browser. The file never leaves your device and no request carrying its contents is made.
Why not just replace the commas?
Because commas inside quoted values are part of the data. A blind replacement would split "Smith, Ada" into two columns. Parsing the file properly avoids that.
Is this reversible?
Yes. The TSV to CSV tool converts the result back, and the values are unchanged.
