Convert TSV to CSV
Convert tab-separated values (TSV), like the ones you get from copying out of Excel, to comma-separated CSV format.
Processed on your device. Nothing is sent to any server.
Interprets each tab as a column separator and regenerates the same content using commas, correctly escaping values that contain commas or quotes.
Use cases

- Preparing tabular data to import into a tool that requires CSV.
- Normalizing data exported in TSV format.
How it works

Technical details
- It's the most reliable way to turn data copied from Excel or Google Sheets into CSV: when you copy cells, the spreadsheet separates them with tabs.
- Values containing commas, quotes or line breaks are quoted in the resulting CSV; quoted values in the original TSV are read as a single field.
- Empty rows are ignored. The output uses a comma separator and Windows line endings (CRLF), the most compatible 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.
