FAQ
How do I convert a TSV file to JSON?
Paste your TSV data into the input area: the first row is used as column headers and each following row becomes a JSON object. The result appears instantly and can be copied.
What is the difference between TSV and CSV?
TSV uses a tab character as the column separator, while CSV uses a comma. TSV is handy when your data contains commas, as it avoids separator conflicts.
Can I convert JSON back to TSV for Excel?
Yes, the tool works both ways. Paste a JSON array of objects and get TSV that you can paste directly into Excel or Google Sheets.
