Converting JSON to XML is necessary when integrating with legacy systems, SOAP web services, XSLT transformation pipelines or certain APIs that only accept XML format. An online tool avoids writing a conversion script manually.
JSON and XML are two very different data serialization formats. JSON uses braces, brackets and commas. XML uses nested tags with attributes. The conversion follows mapping rules: JSON objects become XML elements, JSON arrays become repeated elements, primitive values become the text content of a tag.
📊 Reference table
| JSON structure | Equivalent XML structure |
|---|---|
| {"name": "Alice"} | <name>Alice</name> |
| {"user": {"name": "Alice"}} | <user><name>Alice</name></user> |
| {"items": [1, 2, 3]} | <items><item>1</item><item>2</item><item>3</item></items> |
| {"active": true} | <active>true</active> |
| {"count": 42} | <count>42</count> |
💡 Practical examples
Example 1: convert a user object
JSON: {"id": 1, "name": "Alice", "email": "[email protected]"} → XML: <root><id>1</id><name>Alice</name><email>[email protected]</email></root>
Example 2: convert a product array
JSON: {"products": [{"id": 1}, {"id": 2}]} → XML: <products><product><id>1</id></product><product><id>2</id></product></products>
Example 3: SOAP integration use case
SOAP APIs require XML. Generate your payload in JSON in your code, then convert it to XML with the tool before sending it to the SOAP service.
