JSON to XML Conversion
Converting JSON to XML is common when integrating modern JSON-based APIs with legacy systems that use XML for data exchange. Many enterprise systems, SOAP web services, and document management tools still require XML format.
The conversion maps JSON objects to XML elements, JSON arrays to repeated child elements, and primitive values to element text content.
JSON vs XML: Key Differences
JSON and XML serve the same purpose — structured data representation — but with different trade-offs. JSON is more compact, easier to read, and natively supported in JavaScript. XML supports attributes, namespaces, comments, and mixed content that JSON cannot represent.
XML's verbosity is a disadvantage for REST APIs but an advantage for document-centric use cases like EPUB, SVG, and office document formats.
Use Cases for XML Output
XML output is required for SOAP web service integrations, Microsoft Office and OpenDocument file formats, RSS and Atom feeds, Android layout files, Maven POM files, and many configuration-driven Java frameworks.
Converting your JSON data to XML allows you to feed it into these ecosystems without manual reformatting.

Frequently Asked Questions
How are JSON arrays converted to XML?
+
JSON arrays are converted to repeated <item> elements. Each array element becomes a separate XML element with the tag name 'item' inside the parent container.
How are JSON keys with special characters handled?
+
XML tag names cannot contain spaces or most special characters. The converter replaces invalid characters with underscores to produce valid XML element names.
What XML declaration is added?
+
The converter prepends <?xml version="1.0" encoding="UTF-8"?> to indicate UTF-8 encoding and XML version 1.0.
Can I convert XML back to JSON?
+
Yes. Use our XML to JSON converter to go in the other direction.
