How to use JSON to CSV

Paste a JSON array of objects (or a single object) into the editor.
Pick your delimiter, decide whether to include a header row, and choose quote handling.
The CSV updates live; click CSV → for a satisfying confirm, then Copy or download data.csv.

Nested objects are flattened with dot notation (address.city), arrays of primitives are joined with ;, and any field containing the delimiter, a quote, or a newline is automatically wrapped in quotes (RFC-4180 style). Everything runs locally in your browser.
