Frequently Asked Questions

Why does my JSON need exactly one root key?
XML documents can only have a single root element, so the top-level JSON object must have exactly one key to map to it.
How do I add XML attributes?
Use keys prefixed with @ in your JSON, e.g. "@id": "1" becomes the attribute id="1".
How are JSON arrays converted, since XML doesn't have an array type?
Each array item becomes a separate sibling element with the same tag name — e.g. "item": [1, 2] becomes <item>1</item><item>2</item> — mirroring how the XML to JSON converter combines repeated tags back into an array.
What does a null value in my JSON become in the XML output?
It becomes a self-closing empty tag, e.g. "note": null turns into <note />, since XML has no direct equivalent of JSON's null.
Can I mix text and child elements under the same key, and will the order be preserved?
Partially — a "#text" key's value is always written before any child elements regardless of where it appears in your JSON, so exact mixed-content ordering isn't guaranteed to match the source.
