Frequently asked

Questions about this tool

Is the CSV / JSON converter free?

Yes — free, no signup, no quota.

Does it use the first row as field names?

By default yes. Toggle 'First row is headers' off if your file has no header row — fields will be auto-named (column1, column2, …).

What separators are supported?

Comma, semicolon, tab, and pipe. Auto-detected from the first line, with a manual override available.

Does it handle quoted values?

Yes. Standard CSV quoting and escape rules (RFC 4180) are honoured: double-quotes wrap values containing separators or newlines, and "" inside a quoted field becomes a literal quote.

Will my data be uploaded?

No. Parsing runs entirely in your browser.
