XML to JSON Conversion — Complete Guide
XML (Extensible Markup Language) has been the backbone of enterprise data exchange for decades, powering SOAP APIs, RSS feeds, SVG graphics, and countless legacy systems. However, modern web development has overwhelmingly adopted JSON as the preferred data format due to its lighter syntax and native compatibility with JavaScript. Converting XML to JSON is a critical task when modernizing legacy APIs, migrating data pipelines, or integrating with third-party services that still communicate via XML.
Our XML to JSON Converter uses the browser's native DOMParser to accurately parse XML documents and transform them into structured JSON objects. Attributes are preserved with an @ prefix, repeated elements are automatically converted to arrays, and text content and nested elements coexist cleanly in the resulting JSON structure.
Key Features
- Attribute Preservation: XML attributes are mapped to JSON keys with an
@prefix for clear distinction. - Automatic Array Detection: Repeated sibling elements with the same tag name are automatically grouped into JSON arrays.
- Type Inference: Numeric and boolean text values are automatically parsed into their native JSON types.
- Error Reporting: Invalid XML is caught immediately with descriptive error messages.
- 100% Client-Side: Uses the browser's native DOMParser — no data is sent to any server.
Frequently Asked Questions
Q: How are XML attributes handled?
A: Attributes are converted to JSON keys prefixed with @. For example, <book category="fiction"> becomes {\"@category\": \"fiction\"}.
Q: Does this handle CDATA sections?
A: CDATA content is treated as regular text content and included in the JSON output.
