JSON to CSV
Open JSON data in Excel
or drop files here
Your files never leave your device: JSON to CSV runs inside your browser, so nothing is uploaded, stored or seen by anyone. It is free and needs no sign-up.
How to use JSON to CSV
- Add your file or files by dragging them onto the box above, or type your content where the tool asks for it.
- Set the options for JSON to CSV if you want something other than the defaults.
- Press the button. The work happens on your device, so there is no upload to wait for.
- Download the result. Your original files are not changed.
Questions and answers
- Are my files uploaded anywhere?
- No. Your browser opens and processes the files itself, and nothing is sent to our servers. You can check this yourself on the How we do it page.
- Can I use it for private spreadsheets and data?
- Yes. The data stays in your browser and is not sent to any server, so it is as private as the file on your own device.
- Is JSON to CSV really free?
- Yes. There is no sign-up, no watermark and no limit on how many files you use it for.
- Does it work on a phone?
- Yes. It works in the browser on phones, tablets and computers. A very large file can be slow on an older phone because everything runs on the device.
- Is there a file size limit?
- We set no limit. The real limit is your device’s memory: if a very large file will not open, try a computer or work in smaller parts.
