While JSON dominates modern API design, many enterprise integration platforms, legacy middleware systems, and configuration formats require XML input. SOAP web services, Apache Camel routes, IBM MQ message schemas, and older SAP integration layers all expect XML payloads. Developers working at the boundary between modern JSON-producing services and legacy XML-consuming systems need reliable JSON-to-XML conversion.

Configuration languages for tools like Ant, Maven, Spring Framework, and Log4j use XML exclusively. When generating configuration programmatically from a JSON data model — in a code generator, a scaffolding tool, or a CI/CD pipeline that produces config files — converting a JSON structure to XML is a necessary transformation step.

This tool uses a JavaScript recursive descent converter that maps JSON objects to XML elements, arrays to repeated sibling elements of the same tag name, and scalar values to text content. The browser's XMLSerializer formats the output. Keys that are invalid XML element names are sanitized automatically.

Common Use Cases

Generating SOAP request payloads

SOAP services require XML envelopes with specific namespace declarations. When prototyping a call to a WSDL-defined service using curl or Postman, building the inner XML payload from a JSON object here and then wrapping it in the SOAP envelope manually is faster than writing the XML by hand for a multi-field request body.

Creating Android string resource files

Android res/values/strings.xml files define UI string constants. A localization workflow that stores translations in JSON (common for web apps using i18next) can convert the JSON string map to XML here to bootstrap the Android strings.xml file before adapting it to the <string name="key">value</string> format.

Producing configuration for Apache Camel routes

Apache Camel integration routes can be defined in XML DSL. Teams migrating a route defined in a JSON-based configuration tool can convert their JSON route definition to XML here as a starting point, then adapt the structure to Camel's routes schema rather than rewriting the entire route from scratch.

Feeding data to legacy ETL systems

Older ETL platforms and enterprise middleware (IBM DataStage, older Talend versions) define flat-file and message connectors that expect XML. Converting a modern JSON API output to XML here bridges the gap without writing a custom connector or requiring a full middleware upgrade.
