FAQ

Is this JSON to CSV converter safe?: Yes. Conversion runs entirely in your browser. Your JSON is not uploaded to our server.
Can I convert nested JSON?: Yes. Nested objects and arrays are stringified into CSV cells so you can open the file in Excel.
Can I convert large JSON files?: For typical API payloads (thousands of rows), yes. Very large files may slow your browser — split or trim if needed.
Do I need to upload my file?: No upload required. Paste JSON text directly. Your data never leaves your device.
