GoodWebTools

JSON ↔ XML

This free JSON to XML tool converts data both ways: paste JSON to get clean XML, or paste XML to get structured JSON. It all runs on your device, so even private payloads never leave your browser.

How to use JSON ↔ XML

  1. 1 Paste or type your JSON or XML into the input box, or use Load file to open a .json or .xml file.
  2. 2 Click JSON → XML or XML → JSON to pick the direction you want.
  3. 3 Watch the converted result appear, syntax-highlighted, as you edit.
  4. 4 Copy the output or download it — your data never leaves your browser.

Frequently asked questions

Is my data uploaded when I convert JSON and XML?

No. The conversion runs entirely in your browser with JavaScript. Nothing is sent to a server, so it's safe for confidential or internal data.

Can I convert XML back into JSON?

Yes. The tool works in both directions — click XML → JSON to turn XML into structured JSON, or JSON → XML to go the other way.

Why does my input show a conversion error?

It usually means the input isn't valid for the source format — for example malformed JSON syntax or an unclosed XML tag. Fix the flagged issue and the result updates automatically.

Does the converter work offline?

Yes. GoodWebTools is a PWA, so once the page has loaded it keeps converting with no internet connection.
