// HOW IT WORKS
JSON → XML uses fast-xml-parser's XMLBuilder with 2-space indentation. XML → JSON uses XMLParser and XMLValidator to ensure the input is well-formed before parsing. Both run client-side.
// FAQ
How are JSON attributes vs children handled?
By default, all JSON properties become child elements. To produce XML attributes, prefix keys with @ (a fast-xml-parser convention).
Can I convert XML with namespaces?
Yes. Namespace declarations come through as attributes on the relevant elements.
What about CDATA sections?
When parsing XML, CDATA content is preserved as text. When generating XML, special characters are escaped using standard entity encoding.
