About JSON to CSV Converter

Paste a JSON array of objects and get a properly quoted CSV with a header row — nested objects are flattened with dot notation and arrays are joined with semicolons.

Everything runs locally in your browser: no upload, no account, and you can download the result as a .csv file or copy it to your clipboard.
