TSV

CSV

Convert tab-separated values (TSV), like the ones you get from copying out of Excel, to comma-separated CSV format.

Interprets each tab as a column separator and regenerates the same content using commas, correctly escaping values that contain commas or quotes.

Use cases

Converting text copied from Excel or Google Sheets into valid CSV.
Preparing tabular data to import into a tool that requires CSV.
Normalizing data exported in TSV format.

Frequently asked questions

Does it auto-detect the input separator?: No, this tool assumes the input is tab-separated; if your data uses a different separator, the result may not be what you expect.
