CSV ⇄ TSV Converter
About CSV ⇄ TSV
The CSV and TSV converter switches table delimiters without flattening quoted data. CSV is common for downloads and imports, while TSV is convenient when cells contain many commas or need to be pasted into spreadsheets.
How it works
Structural conversion
The source is parsed into rows and cells before the target delimiter is emitted, so commas or tabs inside quoted fields remain part of the value.
Both directions
Use the swap control to convert comma-separated data to tabs or turn tab-separated text back into conventional CSV.
Safe quoting
The output quotes values only when required by their content and preserves escaped quotes, Unicode and multiline cells.
Frequently asked questions
Is TSV just CSV with tabs?
Conceptually yes, but correct conversion must still parse quoting so delimiter characters inside cells are not mistaken for separators.
Can I paste TSV into Excel or Sheets?
Yes. Tab-separated rows are commonly recognized when pasted into spreadsheet applications.
Is data uploaded?
No. Conversion runs locally.
