JSON をオンラインで XML に変換：スマートな型マッピングと整形出力、アップロード不要
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.

Prefix the key with @_: {"book": {"@_id": "1", "title": "Refactoring"}} produces <book id="1"><title>Refactoring</title></book>.
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.
Yes. The output starts with the XML declaration, elements are properly nested and escaped, and special characters such as <, >, and & are entity-encoded automatically.
