Frequently Asked Questions

Which conversions are supported?

Bidirectional conversion between CSV, TSV, and JSON, as well as CSV ↔ TSV.

Is the header row supported?

Yes. With 'First Row Is Header' checked, CSV/TSV to JSON produces an array of objects; JSON to table auto-extracts headers.

How are quoted or delimited contents handled?

Quote escaping and fields containing delimiters or newlines are handled automatically.

Is data sent to a server?

No. Conversion happens entirely in your browser.
