Convert JSON to XML

Common scenarios where JSON to XML conversion is needed:

• Legacy System Integration: Connect modern JSON APIs with older enterprise systems that only accept XML data feeds.
• SOAP Web Services: SOAP APIs require XML, so JSON from REST APIs often needs conversion for SOAP integration.
• Industry Standards: Many industries mandate XML formats: HL7 for healthcare, XBRL for finance, ONIX for publishing, and more.
• XML Schema Validation: When data must conform to an XSD schema, converting to XML enables automated validation.
• XSLT Transformations: If you need to apply XSLT transformations, the source data must be in XML format.

JSON structures map naturally to XML elements:

{
  "books": [
    {
      "title": "The Great Gatsby",
      "author": "F. Scott Fitzgerald",
      "price": 12.99
    },
    {
      "title": "1984",
      "author": "George Orwell",
      "price": 14.50
    }
  ]
}

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <books>
    <item>
      <title>The Great Gatsby</title>
      <author>F. Scott Fitzgerald</author>
      <price>12.99</price>
    </item>
    <item>
      <title>1984</title>
      <author>George Orwell</author>
      <price>14.50</price>
    </item>
  </books>
</root>

JavaScript Object Notation uses a minimal syntax to represent data structures:

• Objects: Key-value pairs in curly braces {}
• Arrays: Ordered lists in square brackets []
• Values: Strings, numbers, booleans, null, objects, or arrays

Extensible Markup Language uses tags to define elements in a hierarchical structure. Key XML concepts:

• Elements: Opening and closing tags like <book>...</book>
• Attributes: Metadata within tags like <book id="1">
• Root Element: Every XML document has exactly one root element
• Declaration: Optional header specifying version and encoding
