What the JSON to XML converter does
This free tool turns JSON data into clean, well-formed XML right inside your browser. It is a live two-pane converter: JSON goes in the input pane on the left, and matching XML wrapped in a single root element builds in the output pane on the right as you type, with no Convert button to press. Inline validation catches syntax errors and shows a clear message instead of failing quietly. Paste an API response, a config snippet, or any block of JSON, and you get the XML back instantly. It helps developers feeding data into XML-based systems, integration engineers bridging modern JSON APIs with older SOAP or enterprise services, and anyone who needs an XML version of data they already have in JSON.
The conversion follows predictable rules. Each object key becomes a nested tag, so the shape of your data carries straight over. Arrays become repeated item elements, meaning every entry in a list is written out as its own tag rather than collapsed into one. Because XML allows only one top-level element, the result is always wrapped in a root tag. When it looks right, Copy puts the XML on your clipboard and Download saves it as a file, while Load example and Clear help you experiment quickly.
How to use it
- Paste or type your JSON into the Input pane on the left, or press Load example to fill in sample data.
- The XML appears in the Output pane on the right as you type. Conversion is live, so there is nothing to click to run it.
- If your JSON is incomplete or malformed, the output shows a clear error pointing to the problem. Fix the offending part and the XML refreshes on its own.
- Use Copy to grab the formatted XML, or Download to save it as a file. Clear empties both panes when you want to start over.
A quick example
Given {"book": {"title": "Atlas", "tags": ["new", "sale"]}}, you get a book element containing a title tag plus two repeated tags elements, one for each array value, all sitting inside the root.
Everything runs in the browser, so your data stays private on your own device. The tool is free, needs no sign-up, and works on any phone, tablet, or laptop with a browser.
Frequently asked questions
- How are JSON objects and arrays turned into XML?
- Each object key becomes a nested tag holding its value, so structure is preserved level by level. Arrays become repeated elements, where every item in the array is written out as its own tag with the same name.
- Why is everything wrapped in a root element?
- Valid XML must have exactly one top-level element, while JSON can start as an object or an array. The converter adds a single root element so the output is always well-formed and ready to parse.
- Is my JSON sent to a server?
- No. The conversion runs entirely in your browser, so your JSON never leaves your device and nothing is uploaded anywhere.
- What happens if my JSON has a syntax error?
- The output pane shows a clear error instead of XML, pointing to the position or line where the parse failed, so you can jump straight to the missing comma or stray bracket. Fix it and the XML reappears on its own.
- Can I try it without pasting my own JSON, and can I save the result?
- Yes. Load example fills the input with sample JSON so you can see the XML build instantly, and Clear resets both panes. When the output looks right, Copy puts it on your clipboard and Download saves it as an .xml file.
