XML Formatter
Format and minify XML data
What is XML and Why Format It?
Extensible Markup Language (XML) is a standard for data storage and transport, designed to be readable by both humans and machines. Unlike HTML, which has predefined tags, in XML you create your own tags to describe your data's structure. An XML Formatter (or Pretty Printer) organizes these tags hierarchically to make them easier to read.
XML vs. JSON
While JSON is the dominant standard for modern web APIs, XML is still widely used in enterprise systems, financial services, and complex configuration files. XML offers advanced features like Namespaces and robust validation schemas (XSD).
Well-Formed Documents
An XML file must be "well-formed" to be processed. This means every opening tag must have a corresponding closing tag, and elements must be correctly nested. Our tool helps you visualize this structure and visually identify nesting errors.
Privacy: 100% Local Processing
XML files often carry sensitive structured data. At Octovelo, your XML never leaves your browser. All indentation and formatting occur locally on your device. No information is sent to our servers, ensuring full compliance with privacy and data security policies.
