XML to JSON
Convert XML documents to JSON format. Preserves attributes, handles nested elements, and detects arrays automatically.
About XML to JSON Conversion
Converting XML to JSON is essential when modernizing legacy systems, consuming SOAP web service responses in JavaScript applications, or migrating XML-based data stores to document databases like MongoDB. XML to JSON conversion is the most common data transformation in enterprise system modernization, enabling legacy XML-based services to integrate seamlessly with modern REST APIs and JavaScript frameworks. This converter preserves XML attributes (prefixed with @), handles repeated elements as arrays, and correctly processes nested hierarchies.
XML to JSON Mapping Rules
The conversion follows established conventions: XML element names become JSON property keys, text content becomes string values, and XML attributes are preserved with an @ prefix (e.g., @id, @class). When multiple sibling elements share the same tag name, they are automatically grouped into a JSON array. Mixed content (text interspersed with child elements) stores the text content under a special #text key. Empty elements become null, and the root element wraps the entire JSON output.
Unlike JSON, XML supports namespaces, processing instructions, CDATA sections, and entity references -- features that have no direct JSON equivalent. During conversion, namespace prefixes are preserved in element and attribute names, CDATA content is extracted as plain text, and entity references are decoded to their character equivalents. For complex XML documents with mixed namespaces, consider using XPath or XSLT for more granular control over the transformation before converting to JSON.
