CSV to TSV Converter

CSV to TSV Converter rewrites comma-separated data as tab-separated data, the format that pastes cleanly into spreadsheets, databases and many command-line tools. It re-parses every field — including quoted values that contain commas, quotes or line breaks — and re-emits them with tab separators, removing the quoting that comma files need.

Conversion runs entirely in your browser as you type. Nothing is uploaded, so it is safe for private exports and large files alike.

Why convert CSV to TSV?

Tab-separated values avoid the single biggest headache of CSV: fields that contain commas. Because tabs almost never appear inside ordinary data, TSV rows are unambiguous and many tools can split them without a full CSV parser.

TSV is also the format your clipboard uses when you copy a range out of Excel or Google Sheets, which is why pasting TSV back into a sheet drops each value into its own cell automatically.

How quoting is handled

The converter fully parses the CSV first, honouring double-quoted fields, escaped quotes ("") and embedded newlines. It then writes plain tab-separated output. If a value itself contains a tab, newline or quote, it is quoted in the TSV so the structure still round-trips.

All values are treated as text. Numbers, dates and booleans are passed through unchanged so nothing is reformatted or rounded.

Frequently asked questions

Does it handle commas inside quoted fields?
Yes. Quoted fields containing commas, line breaks and escaped quotes are parsed correctly before being re-emitted as tab-separated values.
Will TSV paste into Excel correctly?
Yes. Tab-separated text is exactly what Excel and Google Sheets expect on the clipboard, so each value lands in its own cell.
Is my data uploaded?
No. The conversion happens locally in your browser, so your data never leaves your device.
