JSON is the data format of web APIs and app settings: nested objects and lists in plain text.

Questions

How do I convert CSV to JSON?
Choose your CSV files or drop them on this page, check that JSON is selected, then select Convert and save the result. It works the same on a phone or a computer, and the files never leave your device.
Is it safe to convert CSV to JSON here?
Yes. The conversion runs in your browser, so your CSV files aren't uploaded to a server, and nothing is stored or logged.
Can I convert several CSV files at once?
Yes. Add as many as you like and they convert together; when there are several results you can save them all as one ZIP.
