JSON to XML Converter

Bidirectional JSON to XML and XML to JSON conversion. Configure root element, XML declaration, indentation, and attribute conventions. Runs entirely in your browser — your data never leaves your machine.

Published May 29, 2026

All interactive tools run entirely in your browser. Your data never leaves your device.

How It Works

Paste JSON to generate XML, or paste XML to parse it into JSON. The converter handles nested objects, arrays, attributes (via @ prefix convention), text content (via #text key), and XML special character escaping.

Features

  • Bidirectional conversion: JSON → XML and XML → JSON
  • Configurable root element: choose the wrapper tag name
  • XML declaration toggle: include or omit <?xml?> processing instruction
  • Attribute convention: keys prefixed with @ become XML attributes
  • Text content key: #text maps to element text content
  • Type inference: XML values automatically parsed as numbers, booleans, or null
  • Array handling: repeated elements become JSON arrays
  • XML entity escaping: proper &amp;, &lt;, &gt;, &quot;, &apos; handling
  • 5 example payloads: simple objects, nested data, arrays, attributes, config files
  • Private: runs entirely in the browser — no data transmitted

Use Cases

  • Converting API responses between JSON and XML formats
  • Migrating legacy XML configurations to JSON
  • Generating XML feeds or payloads from JSON data
  • Debugging and inspecting XML documents as JSON
