JSON to XML Converter

The JSON to XML Converter maps a JSON structure onto XML elements.

Mapping rules

JSON	XML
Object	Nested elements; the key becomes the element name
Array {"a":[1,2]}	<a>1</a><a>2</a> (repeated elements)
String / number / boolean	Element text
null, empty object, empty string	Empty element <x/>
Empty array	Omitted

Example

{ "user": { "id": 1, "roles": ["admin", "editor"] } }

<root>
  <user>
    <id>1</id>
    <roles>admin</roles>
    <roles>editor</roles>
  </user>
</root>

Options & notes

• Root and Array item — the wrapping element names.
• XML declaration — insert <?xml version="1.0"?>.
• Keys that are not valid XML element names (spaces, @, leading digit) are adjusted automatically and reported.
