Handles flat JSON arrays

Input should be a JSON array of objects — the standard API response format. Keys from the first object become your CSV column headers automatically.

Ready for Excel and Sheets

The output CSV opens directly in Excel, Google Sheets, or any spreadsheet tool. Choose comma, semicolon, or tab to match your preferred app.

Frequently asked questions

Can I convert JSON to CSV without uploading the file?

Yes. Rawsort's JSON to CSV converter runs entirely in your browser. Your JSON data is never sent to any server.

What JSON format does the converter accept?

The converter expects a JSON array of objects — the standard format returned by most APIs. Each object becomes a row, keys become headers.

Can I choose the CSV delimiter?

Yes. You can choose comma, semicolon, or tab before converting. Useful for European Excel versions that default to semicolons.

Does it work with large JSON files?

Yes. The converter handles large JSON arrays in milliseconds since it runs natively in your browser with no server round-trip.
