JSON to XML converter
Convert JSON data to XML format or XML documents to JSON — with configurable root element names, array handling, and attribute mapping options for integration and data migration tasks.

When a REST API returns JSON but a legacy system expects XML, paste the JSON response here to convert it to XML format. Configure the root element name to match the schema the legacy system expects.
For JSON-to-XML, the converter maps JSON keys to XML elements, arrays to repeated elements, and nested objects to nested element trees. For XML-to-JSON, it parses the document and maps elements to JSON keys and arrays.
Data is processed in the browser. Avoid converting payloads that contain sensitive user records, credentials, or private keys.
JSON and XML have different structural models. JSON arrays with mixed types, JSON null values, and XML attributes do not have direct equivalents in both directions. Review converted output for structural correctness before use in production systems.
