Specifications

How JSON → XML Works

  • Parses JSON properties and generates hierarchical XML tags.
  • Handles array sequences by creating repeating XML element nodes.
  • Escapes XML special entities (&, <, >, ", ').
Demonstration

Example Input & Output

Wraps JSON data in a valid XML declaration and root tag, converting object keys into nested XML tags and arrays into repeating child elements.

  }
}
