Format XML with clear indentation for readability.

Formatted
In-depth explanation
Paste XML to validate and pretty-print it with consistent indentation. Invalid markup shows a clear error message. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
The tool reports a parse error so you can fix the markup first. It only changes whitespace between elements for readability — element content is preserved.
Formatting runs locally in your browser. Tweak the inputs above to compare options, then copy or note the result you need.
Well-formed XML needs matching tags and a single root. HTML is often not well-formed XML; do not expect a random webpage to pretty-print here. Entity encoding and namespaces can also cause parse errors.
Formatting adjusts whitespace between elements. It will not “fix” business logic in the document. Large files are limited by your browser’s memory, not by an upload to Utiio.
