JSON to XML — Complete Guide
XML (Extensible Markup Language) remains essential in enterprise integrations, SOAP web services, configuration files (Maven, Android manifests), and document formats (DOCX, XLSX are ZIP archives of XML). Converting JSON to XML is a common need when integrating modern REST APIs with legacy XML systems.
JSON vs XML Structure
JSON: XML:
{"name":"Alice","age":30} → <item><name>Alice</name><age>30</age></item>
Handling Arrays
JSON arrays map to repeated XML elements. Each array item gets the item tag you specify. Nested arrays are recursively converted.
Using Attributes
XML attributes are more compact than child elements for simple scalar values. Enable @ keys as attrs to map JSON keys prefixed with @ to XML attributes — following the popular BadgerFish and Abdera conventions.
