What is JSON to XML Converter?

JSON to XML Converter transforms data from JSON (JavaScript Object Notation) into XML (eXtensible Markup Language). XML is a structured markup language widely used for data exchange, configuration files, web services, and document storage. Converting JSON to XML enables compatibility with systems that require XML format while preserving the original data structure and hierarchy.

Use this converter to quickly transform JSON API responses, configuration data, or any JSON structure into well-formed XML. The tool automatically handles proper XML escaping, element naming conventions, and maintains data types including strings, numbers, booleans, arrays, and nested objects.

JSON to XML Conversion Examples

Below are examples of JSON to XML conversion. Each example demonstrates how the converter transforms JSON data into valid XML format while maintaining data integrity and structure.

Input JSON:

{
  "user": {
    "name": "John Doe",
    "age": 30,
    "active": true,
    "email": "[email protected]"
  },
  "roles": ["admin", "user"],
  "lastLogin": null,
  "preferences": {
    "theme": "dark",
    "notifications": true
  }
}

Output XML:

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <user>
    <name>John Doe</name>
    <age>30</age>
    <active>true</active>
    <email>[email protected]</email>
  </user>
  <roles>
