JSON to XML Converter
Convert JSON objects and arrays into well-formed XML markup.
Convert JSON to XML
Many enterprise systems, SOAP services, and legacy integrations still speak XML. This converter maps each JSON key to an XML element, repeats elements for array items, and escapes reserved characters so the output is always well-formed.
Mapping rules
- Objects become parent elements with child elements
- Array items repeat the element name
- Primitive values become element text content
- Reserved characters (< > & ") are escaped automatically
Well-formed output
The result begins with an XML declaration and wraps everything in a single root element, satisfying the rule that valid XML has exactly one root. Invalid element names are sanitised to keep the document parseable.
JSON vs. XML
JSON is lighter and maps directly to data structures, which is why it dominates modern web APIs. XML remains common in document-centric formats, configuration, RSS, and older enterprise stacks. Converting between them lets you bridge new and legacy systems without rewriting either side.
