Frequently Asked Questions
How do I convert JSON to CSV online?▾
Paste your JSON array of objects into the input field and click "Convert to CSV". The CSV output appears instantly and you can copy or download it with one click.
Does this tool handle nested JSON objects?▾
Yes. Nested objects are automatically flattened using dot notation. For example, {"address":{"city":"NYC"}} becomes a column named "address.city".
What happens if my JSON objects have different keys?▾
The converter collects all unique keys across every object to build the CSV headers. Missing values in any row are left as empty fields.
Is my JSON data safe when using this converter?▾
Yes. All conversion happens entirely in your browser. No data is ever sent to a server.
