How do I convert JSON to CSV?

Paste your JSON array into the input area, choose a delimiter (comma, tab, or semicolon), and click Convert. The CSV output appears instantly and you can copy or download it. No account or signup required.

Does it handle nested JSON objects?

Yes. Nested objects are automatically flattened using dot notation. For example, {"address": {"city": "NYC"}} becomes a column header "address.city" with value "NYC". Arrays are joined with semicolons.

Is my data safe when converting JSON to CSV?

Yes. Unlike online converters that upload your data, this tool processes everything in your browser using pure JavaScript. Your JSON data never leaves your device — no server, no cookies, no tracking.

What JSON format does the converter accept?

The converter accepts a JSON array of objects, like [{"name":"Alice","age":30},{"name":"Bob","age":25}]. Each object becomes a row and each key becomes a column header. All unique keys across all objects are included.
