How to Convert JSON to XML
JSON to XML
When to Convert JSON to XML
Transform JSON data into XML for legacy integrations, SOAP services, enterprise middleware, and systems that require XML payloads instead of JSON.
Real-World Examples
REST API JSON response → XML for a SOAP bridge
{"user":{"name":"Ada"}} → nested XML elements
Config object → XML config file for legacy deployment tools
Common Mistakes
- JSON keys starting with numbers or containing spaces — may need sanitization for valid XML tag names
- Expecting attributes round-trip without checking XML to JSON conversion rules
- Arrays mapping to repeated elements vs wrapper elements — review output structure
Developer Tips
- Validate JSON before converting
- Convert back with XML to JSON to verify structure for your integration
- Declare XML namespaces manually if your target schema requires them
Frequently asked questions
What root element is used?
JSON is wrapped in a root element. Nested objects become child elements.
How are arrays represented?
Array items typically become repeated child elements under their parent tag.
Are XML attributes generated?
This conversion uses element-based mapping. Use XML to JSON to see how attributes are represented on the reverse path.
