Paste any XML document and see it formatted, validated, and navigable as an interactive tree — all inside your browser with no uploads required.

Paste minified or messy XML and the viewer instantly formats it with clean indentation and line breaks.

Tree Navigation

Switch to tree view to expand and collapse XML nodes for fast navigation of deeply nested documents.

Syntax Validation

Fully Private

All processing runs locally in your browser. Your XML data is never sent to any external server.

How this Online XML Viewer works

This XML viewer renders well-formatted, syntax-highlighted XML markup in your browser for easy inspection and navigation. Paste raw or minified XML into the editor and the tool immediately formats it with consistent indentation and color-coded tags, attributes, and values. A switchable tree view lets you expand and collapse nodes to explore deeply nested document structures.

Everything runs locally in your browser using JavaScript parsing libraries. Your XML data is never transmitted to any server, making the tool suitable for viewing configuration files, API responses, and data exports that may contain sensitive system information or credentials.

The viewer supports large XML documents and handles standard XML features including namespaces, CDATA sections, processing instructions, and XML comments. It is particularly useful for inspecting SOAP responses, RSS and Atom feeds, SVG files, and build configuration formats such as Maven POM or Ant build files without installing a dedicated XML editor.
