Is JSON to CSV free to use?
Yes. This tool is free to use in your browser and does not require an account.
Are my files private?
JSON to CSV uses Papa Parse and native JSON in the browser. Selected files are processed locally when the required browser features are available, while application, library, model, security, and limited analytics requests may load separately.
What limits should I know about?
1 file · 50 MB max. Very large, encrypted, damaged, or unusual files may not be supported by every browser.
What JSON shape works best for CSV conversion?
An array of objects with consistent keys works best because each object becomes a row and each key becomes a column.
Can I paste JSON instead of uploading a file?
Yes. The tool accepts pasted JSON text as well as a JSON file.
