FAQ

This tool works best with arrays of flat objects. Deeply nested structures may not map cleanly to CSV.

Is my JSON sent to a server?

No. All processing stays in your browser.

Can I use this CSV in Excel or Google Sheets?

Yes. Copy the CSV output and paste it into a spreadsheet, or save it as a .csv file.

This tool is for quick one-off JSON-to-CSV conversion during development, debugging, or data prep - no desktop app required.

Common use cases

Limitations
