Where does TSV data come from?

TSV is the format used when you copy cells from Excel or Google Sheets. Pasting spreadsheet data directly into the TSV input box gives correct results.

Is my data uploaded to a server?

No. Everything runs locally in your browser using JavaScript. Your data never leaves your device.

What if a field contains a tab?

Tab characters inside field values are treated as delimiters in standard TSV. There is no standard quoting mechanism for TSV — if your data contains tabs within fields, use CSV format instead.

Can I do the reverse — CSV to TSV?

Yes — use the CSV to TSV Converter tool.
