What is Free XML Beautifier & Formatter Online?

XML Beautifier is a utility for formatting and validating eXtensible Markup Language (XML) data. XML is widely used for configuration files, data exchange between systems, and web services. When XML is minified or poorly structured, it becomes difficult for humans to read and debug. This tool takes any valid XML and applies consistent indentation and line breaks to make the structure clear.

How it works

The tool uses the browser's native `DOMParser` to validate the XML structure. If valid, it then uses a formatting algorithm to apply consistent indentation (2 spaces per level) and line breaks between tags.

Features & Benefits

  • Formats messy XML into human-readable text
  • Validates XML structure and shows parsing errors
  • Indents nested tags for better readability
  • 100% private — happens entirely on your machine

Frequently Asked Questions

Does it validate my XML?

Yes. If the XML is malformed, the tool will display a parsing error message explaining what went wrong.

Is my XML data safe?

Yes. The beautifier runs entirely in your browser. No data is sent to any server.
