How It Works

The converter analyzes your JSON structure and creates equivalent XML representation while maintaining data hierarchy and relationships. It handles special cases like arrays, nested objects, and attributes to ensure accurate conversion.

Steps

  1. Input JSON data is validated for correct syntax
  2. JSON structure is analyzed for conversion mapping
  3. XML structure is generated with proper nesting
  4. Attributes and namespaces are applied if specified
  5. Output is formatted with custom indentation
  6. Final XML document is validated for compliance

Limitations

  • Maximum file size: 10MB
  • Complex circular references not supported
  • Some JSON-specific data types may be simplified

Examples

Simple Object Conversion

Converting a basic JSON object to XML format

Input:

{
  "person": {
    "name": "John Doe",
    "age": 30,
    "email": "[email protected]"
  }
}

Output:

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

Array Handling

Converting JSON arrays to repeated XML elements

Input:

{
  "products": {
    "category": "Electronics",
    "items": [
      {"id": 1, "name": "Laptop"},
      {"id": 2, "name": "Phone"}
    ]
  }
}

Output:

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <products>
    <category>Electronics</category>
    <items>
      <item>
        <id>1</id>
        <name>Laptop</name>
      </item>
      <item>
        <id>2</id>
        <name>Phone</name>
      </item>
    </items>
  </products>
</root>
