What is XML formatting?

Adding proper indentation and line breaks to make hierarchical XML structure readable.

This tool checks well-formedness: proper tags, correct nesting, and valid characters.

JSON is simpler for web APIs. XML supports attributes, namespaces, and schemas for enterprise systems.

What is the difference between well-formed and valid XML?

Well-formed XML follows basic syntax rules (matching tags, proper nesting). Valid XML additionally conforms to a schema (DTD or XSD) that defines allowed elements and structure.

How do I convert XML to JSON programmatically?

Use libraries like xml2js (Node.js), xmltodict (Python), or Jackson (Java). Note that XML attributes and mixed content have no direct JSON equivalent, so conversion may lose some structural information.
