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 the JSON to XML converter does

This free tool turns JSON data into clean, well-formed XML right inside your browser. Paste an API response, a config snippet, or any block of JSON, and you get matching XML back wrapped in a single root element. 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.

How to use it

Paste or type your JSON into the Input box at the top.
Watch the XML appear in the Output box below as you type, or press Convert to run it.
Check the nesting: object keys become tags and array entries become repeated elements under a shared name.
Copy the formatted XML and drop it into your editor, request, or file.

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. If your JSON is incomplete or malformed, fix the offending part and the output refreshes automatically.

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.
