Frequently Asked Questions

What JSON structure works with this converter?
The converter works best with a JSON array of flat objects, e.g., [{"name":"Alice","age":30},{"name":"Bob","age":25}]. Keys of the first object are used as CSV headers.
Does it handle nested objects?
Nested objects are serialised as JSON strings within the CSV cell. For complex nested structures, consider flattening the JSON first.
Can I open the output directly in Excel?
Yes. The generated CSV uses comma delimiters and properly quotes fields that contain commas, making it fully compatible with Excel, Google Sheets, and most CSV readers.
