FAQ – XML Formatter
What is XML?
XML (eXtensible Markup Language) is a markup language for storing and transporting structured data. It uses custom tags to define data elements.
Is my data safe?
Yes. All processing happens in your browser. Nothing is sent to any server.
Why is my XML invalid?
Common errors: unclosed tags, mismatched tag names, missing root element, unescaped special characters (&, <, >), or missing XML declaration.
What's the difference between XML and HTML?
XML is strict (all tags must close, case-sensitive) and used for data. HTML is lenient and used for web page display. XML lets you define custom tags.
Can I use this for SVG files?
Yes. SVG is XML-based, so you can paste SVG code here to format, validate, or explore its structure.
What is the tree view?
Tree view shows XML as a collapsible node hierarchy. Click elements to expand/collapse for easy navigation of nested structures.
