Frequently Asked Questions
- What XML schema does it produce?
- The output is well-formed XML. By default, JSON keys become element names and string values become text content.
- Can I set the root element name?
- Yes. Configure the root element name in the options panel (default: 'root').
- Are JSON arrays converted correctly?
- Array elements become repeated sibling elements. The parent element name is used for each item.
- Can JSON keys become XML attributes instead of elements?
- Yes. In Pro/Business options, you can configure which keys are rendered as attributes vs. child elements.
- Is the XML validated after conversion?
- Basic well-formedness is checked. Full schema validation (XSD) is not performed.
