Conversion Details

  • If the JSON document has more than one property on the first level, the converted XML document will have an additional root element called <JSON>.
    For example, the following JSON document:
    {
       "personnel": {
        "person": [
          {"name": "Boss"},
          {"name": "Worker"}
        ]
      },
      "id":"personnel-id"
    }
    it is converted to:
    <?xml version="1.0" encoding="UTF-8"?>
    <JSON>
      <personnel>
        <person>
          <name>Boss</name>
        </person>
        <person>
          <name>Worker</name>
        </person>
      </personnel>
      <id>personnel-id</id>
    </JSON>
  • If the JSON document is an array, the converted XML document will have a root element called <array> and for each item within the array, another <array> is created.
    [
      {"name": "Boss"},
      {"name": "Worker"}
    ]
    it is converted to:
    <?xml version="1.0" encoding="UTF-8"?>
    <array>
      <array>
        <name>Boss</name>
      </array>
      <array>
        <name>Worker</name>
      </array>
    </array>
  • If the name of a JSON property contains characters that are not valid in XML element names (for example, $), then the invalid characters will be escaped as its hexadecimal equivalent in the converted XML.
    {"$id": "personnel-id"}
    is converted to:
    <_X24_id>personnel-id</_X24_id>
