JSON String FAQ

Is the JSON String free?

Yes. The JSON String is free with no trial limit, subscription, or watermark on downloads. You can use it for personal and commercial projects without creating an account.

Are my files uploaded to your servers?

Many EditTools pages process files in your browser, so data never leaves your device. When server processing is required, files are handled over encrypted connections and removed according to our privacy policy.

Which file formats are supported?

This page supports JSON, YAML, XML, and CSV. If an upload fails, check that the file is not corrupted and that it matches the accepted types shown in the upload area.

Do I need to install software?

No installation is required. Open the JSON String in a modern browser, upload your file, and download the result. It works on desktop and mobile without plugins.

Can I use this tool on my phone or tablet?

Yes. The layout is responsive on iOS and Android browsers. Upload from your gallery or files app, adjust settings, and save the processed file back to your device.

How is this different from desktop editors?

Desktop suites offer more filters but take time to install and learn. The JSON String focuses on one job—JSON data structures for APIs and configs—so you finish quickly from any computer.
