Frequently Asked Questions
Paste your JSON data or upload a JSON file, click Convert, and your CSV file will be generated and downloaded automatically.
Yes. This online JSON to CSV converter is completely free to use, with no limit on the number of conversions.
Yes. Your JSON data stays on your device the entire time. The conversion to CSV runs locally in your browser, not on a remote server.
Yes. You can either paste JSON data directly or upload a .json file for conversion.
The converter automatically fixes common issues before converting — single quotes instead of double quotes, missing quotes around keys, trailing commas, and smart/curly quotes copied from Word or Google Docs. You don't need to clean up your JSON first.
Yes. If you paste a full API response (for example, a payload with a "data" or "results" wrapper around the actual list), the converter finds the array of records automatically. If the response contains more than one list, you'll be shown the options so you can pick the right one.
Yes. If you paste data as an array of arrays (rows and columns, like a pasted spreadsheet), the first row is used as the column headers automatically and converted into records.
Yes. Nested fields (like an address object or a list of tags inside each record) are automatically flattened into separate columns — for example, "address.city" — since CSV doesn't support nested structures.
No. Since CSV isn't practical to preview as plain text, clicking Convert generates and downloads the CSV file directly to your device.
No. The entire JSON to CSV conversion runs in your browser, so no software, plugin, or app installation is required.
Compatible with all major browsers, including Chrome, Firefox, Safari, and Edge, on desktop or mobile.
