XML to JSON Converter

Convert XML to JSON format.

XML to JSON Conversion

XML and JSON both represent structured data, but JSON is simpler and more common in modern web development. This tool converts XML documents to equivalent JSON structures. Attributes become properties, child elements become nested objects.

The conversion isn't always 1:1. XML supports features like attributes, mixed content, and namespaces that don't map cleanly to JSON. Simple XML structures convert well; complex documents may need manual adjustment.

Conversion Notes

  • Attributes typically become @attribute properties
  • Text content becomes #text or the value directly
  • Repeated elements become arrays

Understanding XML to JSON Conversion

XML (eXtensible Markup Language) uses tags and attributes to structure data hierarchically, while JSON (JavaScript Object Notation) uses key-value pairs and arrays. Converting between them requires mapping XML elements to JSON objects and attributes to properties. Our converter preserves nesting structure and handles most XML features automatically.

JSON is typically more compact than XML'often 30-50% smaller'because it lacks the verbose opening/closing tag syntax. This makes JSON preferred for web APIs where bandwidth matters, while XML remains common in enterprise systems, SOAP services, and document-oriented applications.

Frequently Asked Questions

How are XML attributes converted?

XML attributes become properties in the JSON object. The conversion depends on the implementation'some converters prefix attribute names with "@" to distinguish them from child elements. Our tool converts attributes to regular JSON properties.

What happens to repeated elements?

When XML contains multiple elements with the same name, they're converted to a JSON array. Single elements become objects. This automatic detection preserves the semantic meaning of your data structure.

Why is my XML showing an error?

XML must be "well-formed"every opening tag needs a closing tag, attribute values must be quoted, and special characters must be escaped. Common errors include unclosed tags, mismatched tag names, and unescaped ampersands or less-than signs.
