Question 1

How are XML attributes handled?

Accepted Answer

This converter focuses on element-based XML structure. XML element content and child elements are converted to JSON. Attributes are not currently included in the output — for attribute-heavy XML, consider preprocessing or using a dedicated XSLT transformation.

Question 2

How are repeated XML elements handled?

Accepted Answer

When multiple sibling elements share the same tag name, they're collected into a JSON array. For example, multiple elements under become an array. Single elements become a string or object value.

Question 3

What happens to XML namespaces?

Accepted Answer

XML namespace prefixes (e.g., ns:element) are preserved in the JSON key names as-is. Namespace declarations (xmlns attributes) are not included in the output.

Question 4

Can I convert JSON back to XML?

Accepted Answer

Yes — click the Swap button to convert JSON back to XML. The output uses the same element-based structure.

Question 5

What XML is supported?

Accepted Answer

Standard well-formed XML. The parser uses the browser's built-in DOMParser which validates XML structure. Malformed XML (unclosed tags, invalid characters) will produce an error with the parser's diagnostic message.

Question 6

How do I convert XML to JSON?

Accepted Answer

Paste your XML document above and click Convert. The tool parses the XML DOM and transforms elements, attributes, and text content into a JSON structure. XML attributes become prefixed keys. The output is valid JSON you can download or copy. For the reverse, use DevDecode's JSON to XML Converter. For XML validation, use the XML Validator.

Question 7

What are the challenges of converting XML to JSON?

Accepted Answer

XML has features JSON lacks: attributes vs elements, mixed content (text + child elements), XML namespaces, comments, and processing instructions. This converter handles common cases but complex XML with mixed content or namespaces may need manual adjustment. Use DevDecode's XML Formatter to inspect the structure before conversion and JSON Formatter to validate the output.
