JSON ⇔ XML Converter

What is the JSON ⇔ XML Converter?

A fast and fully client-side tool to bidirectionally convert between JSON (JavaScript Object Notation) and XML (eXtensible Markup Language).

How to Use

1. Input Data: Paste your JSON or XML content into the left pane.
2. Auto-Detection: The tool will automatically detect the format and display the converted counterpart in the right pane instantly.
3. Manual Mode: You can force the parser direction using the top dropdown menu if needed.
4. Indentation Control: Adjust the target output formatting (2 Spaces, 4 Spaces, Tabs, or Minified).

Terminology

• Attribute Handling: When converting XML to JSON, XML attributes are preserved and prefixed with @_ (e.g. <tag id="1"> becomes {"tag": {"@_id": "1"}}). This matches standard parsers.
• Minification: Selecting the "Minified" option will strip all whitespace and line breaks, producing an ultra-compact string suitable for network payloads.

Security

All parsing, attribute mapping, and text generation happens locally in your browser. Since no data is transmitted to an external server, you can safely paste API keys or sensitive project infrastructure files.
