What JSON formats are supported?

Supports JSON arrays of objects. Each object becomes a CSV row, with keys as column headers. Also supports nested objects (flattened with dot notation).

Can I upload multiple JSON files?

Yes—upload multiple `.json` files and this tool will normalize each as a batch conversion when batch mode is on.

Can I convert large JSON files?

Everything runs in your browser. Extremely large files may take longer to convert, so consider dedicated tooling if you hit performance limits.
