How are JSON keys turned into XML elements?
Each key becomes the name of an XML element, and its value becomes the element content. Object values produce nested elements, primitive values produce text content, and arrays produce repeated sibling elements with the same name. A wrapping root element is added because XML requires exactly one root, while JSON can start with any value type.
What happens to JSON keys that are not valid XML element names?
XML element names cannot start with a digit, contain spaces, or use most punctuation. Keys that violate these rules are sanitized - usually by replacing invalid characters with underscores or by prefixing a letter. Keep this in mind when round-tripping data: the sanitized names will not match the original JSON unless you store the original name in an attribute.
How are arrays represented since XML has no array concept?
Arrays are flattened into repeated elements with the same tag name. For example, an array of three users under a key named user produces three user elements in sequence. This is unambiguous when reading XML in code that knows the schema, but it can be confusing because a single-item array is indistinguishable from a single value when reading the XML directly.
Can JSON properties become XML attributes instead of child elements?
Some converters use a convention where keys prefixed with an at-sign become attributes, and a key like #text holds the element body. This produces compact XML that mirrors common conventions, but it requires you to shape the JSON input accordingly. If you do not control the JSON, expect everything to be emitted as child elements rather than attributes.
Is the XML output well-formed and valid?
The output is always well-formed - tags are balanced, special characters are escaped, and there is exactly one root element. Validity against a specific DTD or XSD schema is a separate concern. Generated XML conforms to whatever shape the JSON had; if you need it to match an existing schema, post-process the result or shape the JSON to align with the schema first.
How are special characters like ampersand and angle brackets handled?
They are escaped to the standard XML entities - ampersand becomes &, less-than becomes <, greater-than becomes >, double quote becomes ", and apostrophe becomes '. Without this escaping, parsers would treat the characters as markup and fail. CDATA sections are sometimes used as an alternative for long blocks of text containing many special characters.
