How do I create XML attributes from JSON?

Prefix the key with @_ — for example { "book": { "@_id": "1" } } becomes . Keys without the prefix become child elements.

Are special characters escaped?

Yes. Characters like &, in values are escaped so the XML stays valid.

JSON to XML Converter

Turn JSON into well-formed, indented XML. Arrays become repeated elements, keys starting with @_ become attributes, and a root element is added when needed.

How to use the JSON to XML Converter

1
Paste JSON
Paste an object or array into the left editor.
2
Name the root
XML needs one root element. If your JSON has several top-level keys or is an array, it's wrapped in the root name you choose.
3
Add attributes
Keys that start with @_ become attributes, e.g. "@_id": 1 becomes id="1".
4
Copy or download
Copy the XML or download it as a .xml file.

Examples

Array of objects with attributes

JSON

{
  "catalog": {
    "book": [
      { "@_id": "1", "title": "A" },
      { "@_id": "2", "title": "B" }
    ]
  }
}

XML

<catalog>
  <book id="1">
    <title>A</title>
  </book>
  <book id="2">
    <title>B</title>
  </book>
</catalog>

Common errors and how to fix them

Invalid JSON: Fix the JSON first — the JSON Validator shows the exact line and column of the error.
Element names look wrong: XML element names can't start with a number or contain spaces. Rename keys like "1st item" to something like firstItem.
