What Is a JSON to XML?

Plenty of enterprise systems, SOAP services, and feed formats still speak XML — SAP integrations, government data feeds, banking APIs, RSS, Atom. Going from a modern JSON internal model to the XML shape these systems want is a structural translation: each object becomes a parent element, each key/value becomes a child element, and arrays repeat the element name once per item.

This converter wraps the result in a configurable `<root>` element. Keys that aren't valid XML names (containing spaces, leading digits, or special characters) are sanitised. Numbers, booleans, and null are emitted as text content — `<count>3</count>` rather than typed attributes.

Frequently Asked Questions

When would I need JSON to XML?
Legacy systems, SOAP APIs, and some enterprise integrations use XML. Converting JSON to XML helps integrate modern APIs with older systems.
How are JSON keys converted to XML?
Object keys become XML element names. Arrays become repeated elements. Values become text content. The root element defaults to <root>.
What happens to invalid XML names?
Keys that aren't valid XML names (e.g., contain spaces) are sanitised. Spaces become underscores; leading digits get an underscore prefix.
