What is the CSV to TSV Converter?

The ByteTools CSV to TSV Converter turns comma-separated data into clean tab-separated values. Paste CSV or drop a file, and the quote-aware parser reads fields exactly as a spreadsheet would — including commas, quotes and line breaks inside quoted fields — before re-emitting each row with tabs between the columns.

  • RFC 4180 quote-aware CSV parsing
  • Custom single-character input delimiters
  • Escape, space-replace or strip embedded tabs and newlines
  • Copy to clipboard or download as .tsv
  • 100% private — nothing leaves your browser

About the CSV to TSV Converter

The ByteTools CSV to TSV Converter turns comma-separated data into clean tab-separated values. Paste CSV or drop a file, and the quote-aware parser reads fields exactly as a spreadsheet would — including commas, quotes and line breaks inside quoted fields — before re-emitting each row with tabs between the columns.

Because TSV has no quoting rules of its own, you decide what happens to tabs or newlines found inside a field: escape them as \t and \n, replace them with a space, or remove them. Semicolon, pipe and custom single-character input delimiters are supported too.

Everything runs 100% locally in your browser — your data is never uploaded to any server. That makes it safe for exports containing customer lists, financial rows or anything else you would rather keep private.

Frequently asked questions

What is the difference between CSV and TSV?

CSV separates columns with commas and uses double quotes to protect fields that contain commas or line breaks. TSV separates columns with tab characters and normally has no quoting at all, which makes it simpler to parse and a favourite for database imports and command-line tools.

How are commas inside quoted CSV fields handled?

The parser follows the standard CSV quoting rules, so a value like "Smith, John" stays one field. In the TSV output it simply appears as Smith, John — commas need no special treatment once the separator is a tab.

What happens if a field itself contains a tab character?

You choose. The default escapes it as \t so no data is lost and the column count stays correct. You can instead replace embedded tabs and newlines with a space, or remove them entirely if a downstream tool cannot handle escapes.

Can I convert semicolon-separated files to TSV?

Yes. Set the input delimiter to semicolon — common in European exports where the comma is the decimal separator — or choose Custom and type any single character, such as a pipe or caret.

Is my data uploaded when I convert it?

No. The conversion runs entirely in your browser with JavaScript. Nothing is transmitted, logged or stored on a server, so confidential spreadsheets stay on your machine.
