Frequently Asked Questions
Why does JSON to XML conversion require a root element?
Valid XML documents must contain exactly one top-level root element enclosing all other tags. The converter wraps your data in a root tag to guarantee well-formedness.
How are JSON arrays converted to XML tags?
JSON array items are mapped to repeating element nodes, typically using the key name of the array or a configurable child element tag like <item>.
What happens if a JSON key contains characters invalid in XML tag names?
Characters that are illegal in XML element names (such as spaces or symbols) are sanitized or substituted with underscores to produce valid XML.
