Frequently Asked Questions

Is this JSON to XML converter free?

Yes — completely free, forever. There's no sign-up, no account, and no usage limits. If you find it useful, a coffee is appreciated but never required.

Is my data safe?

All conversion happens locally in your browser using JavaScript. Your JSON or XML is never uploaded to any server. It's safe to use with sensitive or proprietary data.

What file types are supported?

You can upload or drag and drop .json, .xml, and .txt files. Output can be downloaded as .json or .xml.

Can it handle large files?

Yes — the tool handles files up to 500 MB. Large files are processed off the main thread using Web Workers, so the page stays fully responsive. A progress bar shows reading and conversion status, and very large outputs are delivered as a direct download.
