Converting XML to JSON
XML to JSON conversion is needed when consuming data from legacy APIs, RSS feeds, or SOAP services in modern JavaScript applications. JSON is easier to work with in browsers and Node.js, and its compact format reduces bandwidth usage.
This tool uses the browser's built-in XML parser to ensure the input is well-formed before converting it, which catches malformed XML before it causes downstream errors.
Mapping XML Structures to JSON
The conversion follows these rules: XML elements become JSON object keys. Text content becomes the value. Repeated sibling elements with the same name become arrays. Empty elements become null.
This mapping covers the majority of real-world XML data structures, though some XML features like namespaces, processing instructions, and mixed content (text + child elements) do not have direct JSON equivalents.

Frequently Asked Questions
How are XML attributes handled?
+
This converter focuses on element content. XML attributes are not currently included in the JSON output. The element tag names become JSON keys.
What happens with repeated XML elements?
+
Repeated sibling elements with the same tag name are automatically converted to a JSON array.
Can this handle large XML files?
+
The converter uses the browser's built-in DOMParser, which handles moderately large XML files well. Very large files (10MB+) may be slow depending on your device.
