JSON

    Example

    XML input

    <?xml version="1.0" encoding="UTF-8"?>
<library city="London">
  <book id="1"><title>Notes</title><year>1843</year></book>
  <book id="2"><title>Compilers &amp; Code</title><year>1952</year></book>
</library>

    JSON

    {
  "library": {
    "book": [
      {
        "title": "Notes",
        "year": 1843,
        "@id": 1
      },
      {
        "title": "Compilers & Code",
        "year": 1952,
        "@id": 2
      }
    ],
    "@city": "London"
  }
}

    How it handles tricky cases

    Attributes

    An attribute becomes a key with an @ prefix, so id="1" becomes "@id": 1. When an element has both attributes and text, the text goes in #text.

    Repeated elements

    Elements that repeat become an array. An element that appears only once stays a single value, so code reading the JSON should allow for both shapes.

    Namespaces

    Prefixes stay in the key name, so soap:Body becomes the key soap:Body.

    What isn't kept

    XML comments and processing instructions are dropped. CDATA becomes normal text. In mixed content, where text and child elements alternate, their relative order is not preserved.

    Invalid XML

    The document is validated first, and the error message gives the line and column of the problem.

    Do it from code

    Python with xmltodict:

    import json, xmltodict

with open("in.xml", encoding="utf-8") as f:
    data = xmltodict.parse(f.read())
print(json.dumps(data, indent=2))

    Questions

    Why did my number stay text?

    Values with leading zeros stay text so that codes like 007 aren't changed. You can also turn off detection so every value stays text.

    Is there one standard way to map XML to JSON?

    No. Tools differ on attributes and arrays. This one uses the @ prefix for attributes and #text for element text.

    Is my XML uploaded?

    No. It is parsed on your device.
