About this tool

CSV parsing follows the RFC 4180 quoting rules — fields with commas, quotes, or newlines must be wrapped in double quotes, and embedded quotes are escaped as "".

JSON input must be an array of objects with the same shape. Nested objects or arrays inside a row are serialized back to JSON when converting to CSV.
