XML (eXtensible Markup Language) remains the standard for enterprise APIs, SOAP web services, RSS/Atom feeds, Android resource files, and data interchange in banking and government systems. Our free XML tools let you format messy XML into readable indented output, validate XML syntax, and convert XML to JSON — entirely in your browser.
XML uses opening and closing tags and supports attributes, namespaces, and comments. JSON uses key-value pairs with no redundant tags. JSON is smaller and faster for web APIs; XML is preferred for document-centric or enterprise protocols.
A well-formed XML document follows strict syntax rules: every opening tag must have a matching closing tag, attributes must be quoted, elements must be properly nested, and there must be exactly one root element.
