Convert TSV to CSV format
TSV to CSV converts tab-separated values to comma-separated values entirely in your browser — nothing is uploaded to a server. Output fields are quoted per the standard CSV convention whenever needed: a value containing a comma, a double quote, or a newline is wrapped in double quotes (with any internal quote doubled), so that value is read back as a single column rather than splitting apart in a spreadsheet.
What's the difference between TSV and CSV?
TSV separates values with tabs; CSV uses commas. This tool converts the delimiter from tabs to commas.
Does it support file upload, or only pasted text?
Only pasted text — there's no file picker or drag-and-drop upload.
Is my data uploaded to a server?
No, the conversion happens entirely in your browser.
Does it handle values that already contain a comma?
Yes — any value containing a comma, quote, or newline is automatically wrapped in double quotes in the output, so it's read back as a single column rather than looking like an extra one.
