JSON to XML Tips

Keys starting with @_ become XML attributes - {"@_id": "1"} produces id="1" on the parent tag.
A #text key becomes the text content of its parent tag instead of a child element.
If your JSON top level is an array or a plain value, it is wrapped in a configurable root element (default: root).
The output includes the XML declaration and is pretty-printed with 2-space indentation.

XML requires a single root element, so top-level arrays and plain values are wrapped in a root tag. You can change its name in the Root element field.

true and false become the text "true" and "false", and null becomes an empty element - keeping the XML valid while staying easy to read.
