How XML to JSON Conversion Works

XML and JSON have different data models, so conversion requires mapping conventions:

Elements become JSON object keys
Attributes are prefixed (default: @) to distinguish from child elements
Repeated elements automatically become arrays
Text content becomes the value, or uses a special key (#text) for mixed content
Empty elements become null or empty strings

Handling Attributes

By default, XML attributes are prefixed with @ (e.g., id="5" becomes "@id": "5"). Use "Merge attributes" to include them without a prefix, or customize the prefix in options.

Array Detection

When multiple sibling elements have the same tag name, they're automatically grouped into an array. Enable "Always use arrays" to wrap all child elements in arrays for consistent structure.

Common Use Cases

API Integration: Convert XML API responses to JSON for JavaScript processing
Data Migration: Transform legacy XML data to modern JSON format
Configuration: Convert XML config files to JSON for Node.js or web apps
Debugging: Quickly inspect XML structure in a more readable JSON format
SOAP to REST: Convert SOAP XML responses for REST API compatibility

Frequently Asked Questions

Why are all values strings in the JSON output?

XML doesn't have native data types — everything is text. This converter preserves the original text values. If you need typed values (numbers, booleans), you'll need to post-process the JSON or use a schema-aware converter.

How are namespaces handled?

XML namespaces are preserved as part of the tag name (e.g., ns:element becomes "ns:element"). Namespace declarations are treated as regular attributes.

What happens to CDATA sections?

CDATA content is extracted as plain text. The CDATA wrapper is removed and the content is treated as regular text.

Can I convert JSON back to XML?

Yes! Use our JSON to XML Converter for the reverse conversion.
