Convert XML documents to JSON with configurable attribute prefix, text key, compact mode, and value coercion. Handles nested elements, repeated siblings, CDATA, comments, and processing instructions. Runs entirely in your browser — your data never leaves your machine.

xml json converter parser data serialization

Published May 30, 2026

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

How It Works

Paste XML content and get structured JSON output. The converter parses the XML document, builds a tree, and serializes it to JSON with configurable options for attribute handling, text content, and value coercion.

Features

  • Attribute handling: configurable prefix (default @) for XML attributes
  • Text key: customizable key for mixed-content text nodes (default #text)
  • Compact mode: text-only elements become simple values instead of objects
  • Value coercion: automatically converts true, false, null, and numbers
  • Repeated elements: sibling elements with the same name become JSON arrays
  • CDATA sections: content preserved as text
  • Comments & PIs: gracefully skipped during conversion
  • Self-closing tags: handled correctly (<br/>, <img src="..." />)
  • Stats: element count, attribute count, text nodes, max depth
  • 5 examples: simple elements, attributes, nested structures, mixed content, CDATA
  • Private: runs entirely in the browser — no data transmitted
