DocomintTSV Converter
Convert between CSV (comma-separated) and TSV (tab-separated) data.
Converts comma-separated data to tab-separated (the format Excel and Google Sheets use for direct paste-in) and back — useful when a tool exports one format but the destination you're pasting into expects the other.
Example: A CSV row "Alex,30,Engineer" converts to a tab-separated line, ready to paste directly into a spreadsheet cell as three separate columns.
How it works
- Paste CSV or TSV data
- Pick a direction
- The converted data appears instantly, on your device
Frequently asked questions
Why would I need TSV instead of CSV?
Tab-separated data pastes directly into a spreadsheet as separate cells without needing an import wizard, and it sidesteps comma-escaping issues entirely when your data doesn't contain tabs.
Is my text uploaded anywhere?
No — TSV Converter runs entirely in your browser using JavaScript/WebAssembly. Your text is never sent to a server.
If I paste TSV output into Excel or Google Sheets, does it automatically split into columns?
Yes — both recognize tab characters as column separators on paste, which is exactly why TSV, not CSV, is the format they use internally for copy-paste.
