What if my data contains commas?

Those cells are automatically quoted in the CSV so the commas inside them aren't mistaken for column separators.

Is the header row preserved?

Yes. The row layout is kept exactly; only the delimiter changes from tab to comma.

Will my data be uploaded?

No. Parsing and conversion happen entirely in your browser — the file never leaves your device.

What is TSV?

TSV (tab-separated values) is like CSV but uses tab characters between columns — common in database and spreadsheet exports where values contain commas.

Why convert TSV to CSV?

Many tools and import dialogs expect commas, not tabs. Converting to CSV makes the data portable to Excel, Sheets, and standard CSV parsers.

How the conversion works

Convertur splits each row on tabs and re-serialises it as CSV, wrapping any value that contains a comma, quote, or newline in quotes.
