Frequently Asked Questions
Can I generate XML attributes?
Yes! If you prefix a JSON key with `@_` (e.g., '@_id': 123), it will be converted into an attribute (id='123') rather than a nested tag.
Is the XML output formatted?
Yes, the output is automatically beautified with 2-space indentation and line breaks for maximum readability.
Does it support custom root nodes?
The resulting XML structure mirrors your JSON object. To define a root node, simply wrap your data in a single top-level JSON key.
How are JSON arrays converted to XML?
Arrays are converted into repeating XML elements. For example, `{ 'item': [1, 2] }` becomes `<item>1</item><item>2</item>`.
Is there a limit to nesting depth?
No. The converter handles deep recursion, making it suitable for generating complex XML schemas used in enterprise middleware.
Is my JSON data kept private?
Yes. Like all tools on DevToolsLabs, the conversion is performed client-side. Your data never leaves your machine.
