FAQ

What CSV format is supported?▼

RFC 4180-compliant CSV. Fields with delimiters or quotes must be quoted with double-quote characters. Doubled double-quotes represent a literal quote.

Does JSON to CSV support nested objects?▼

Nested objects are converted to strings. For deeply nested data, flatten your JSON before converting.

Can I change the delimiter to semicolon?▼

Yes. Use the delimiter selector to switch between comma, semicolon, tab, and pipe separators.

Frequently Asked Questions

Does the CSV parser handle quoted fields?

Yes. The parser is RFC 4180-compliant and correctly handles quoted fields containing commas, newlines, or escaped double quotes.

What delimiters are supported?

Comma (,), semicolon (;), tab, and pipe (|) are supported. You can also specify a custom delimiter character.

Can I convert JSON back to CSV?

Yes. The tool works bidirectionally — paste JSON arrays of objects to get CSV output, or paste CSV to get a JSON array. Array keys become column headers.
