Frequently Asked Questions
- How do I create XML attributes from JSON?
- Use keys prefixed with "@_" for XML attributes and "#text" for node text. For example, {"product":{"@_id":"42","#text":"Keyboard"}} becomes <product id="42">Keyboard</product>.
- What happens if my JSON starts with an array?
- Top-level arrays are wrapped in your chosen root tag, and each entry uses the array item tag so the result stays valid XML. This is useful when you need to convert a JSON array to XML for feeds, imports, or API payloads.
