How XML Formatting Works in Software Engineering

XML (Extensible Markup Language) is widely used for configuration files, SOAP web services, RSS feeds, and data interchange. Minified or poorly formatted XML can be difficult to read and debug. This tool parses your raw XML string on the client side, detects parsing errors, and pretty-prints it with customizable indentation and color syntax highlighting.

Privacy Guarantee: All processing is done entirely in your browser using standard DOMParser APIs. Your XML data is never uploaded to any external server.
