XML to JSON Converter

Convert XML to JSON using the @-prefix convention for attributes (compatible with xml2js and xmltodict). Repeated elements become arrays automatically.

Infer types (numbers, booleans, null)

{
  "catalog": {
    "book": [
      {
        "@id": 1,
        "@category": "fiction",
        "title": "XML Developer's Guide",
        "author": "Anonymous",
        "price": 44.95
      },
      {
        "@id": 2,
        "@category": "nonfiction",
        "title": "Midnight Rain",
        "author": "Eva Peretti",
        "price": 5.95
      }
    ]
  }
}

Convention: Attributes are prefixed with @, text content uses #text, comments use #comment.

Arrays: Repeated sibling elements are automatically converted to arrays.

How does XML to JSON conversion work?

XML and JSON model data differently: XML has attributes, mixed content, and repeated elements that have no direct JSON equivalent. This converter follows the widely-used convention where attributes become @-prefixed properties, element text becomes a #text property when mixed with children, and repeated sibling elements collapse into arrays.

The output is compatible with the conventions used by xml2js (Node.js) and xmltodict (Python), so converted documents behave predictably if you feed them to tooling built around those libraries.

When to use it

Use it when migrating an XML-based API to JSON, inspecting SOAP or RSS feeds in a JSON-friendly tool, feeding XML data into JavaScript applications, or quickly checking how a document will look after a programmatic conversion.
