XML Viewer
Format and validate XML data with tree view
The XML Viewer formats raw XML data with proper indentation and offers an interactive tree view for visually navigating hierarchical structures. XML (eXtensible Markup Language) is used in configuration files, SOAP APIs, RSS feeds, SVG graphics, and enterprise data exchange. As XML structures grow complex, a visualization tool becomes essential for understanding element relationships and spotting errors quickly with real-time validation.

๐ฏ Tips
- โธIn tree view mode, click nodes to expand or collapse child elements โ ideal for navigating large XML documents.
- โธAn XML declaration (<?xml version="1.0"?>) isn't required for parsing, but add one if you encounter encoding issues.
- โธCDATA sections contain unparsed content, which is useful when XML wraps HTML or script code.
- โธFor very large XML files, use formatted mode instead of tree view for faster rendering performance.
โ FAQ
Q. It says my XML is invalid
A. Check that tags are properly opened and closed. XML is case-sensitive.
Q. Does it support namespaces?
A. Yes, all standard XML including namespaces is supported.
Q. Can it handle large XML files?
A. Yes, within browser memory limits. For very large files, formatted mode is recommended over tree view.
Q. What's the difference between XML and HTML?
A. XML is a markup language for storing and transporting data with user-defined tags. HTML is for displaying web pages with a predefined set of tags. XML requires all tags to be properly closed and is case-sensitive, while HTML is more lenient.
Q. When should I use XML instead of JSON?
A. XML is better suited for SOAP-based legacy systems, strict schema validation with XSD, documents requiring namespaces, and markup-heavy formats like SVG. For new REST APIs, JSON is the more common choice due to its lighter syntax.
