It’s often used in:

Legacy systems
Enterprise data integrations

🔁 Why Convert JSON to XML?

Many modern systems (web and mobile apps) use JSON, while many legacy systems, enterprise APIs, and government portals still rely on XML.

A JSON to XML Converter helps you:

✅ Exchange data between modern and legacy systems
✅ Integrate REST APIs with SOAP-based applications
✅ Convert app data to XML for document generation
✅ Submit XML-compliant forms or API payloads

🧮 How Does JSON to XML Conversion Work?

During conversion, the structure and key-value pairs of JSON are translated into XML nodes:

JSON Component	XML Equivalent
Object `{}`	Element with nested child elements
Array `[]`	Repeated elements
Key-value pair	Element name = key, value = text node
Attributes (optional)	XML attributes using conventions like `@attrName`
Null value	Self-closing or empty tag
