About XML Formatter
XML Formatter is a free online tool. Beautify and validate XML documents for feeds, sitemaps and configuration. It runs entirely in your browser, so there is nothing to install, no account to create and no watermark added to your result.
How to use XML Formatter
- Paste your code or data into the input box.
- Choose an option or press the action button.
- Read the result, fix any reported error and copy the output.
Worked example
Enter a short sample first to see how XML Formatter behaves, check the result, then run your real content.
Tips for best results
- A single unclosed tag makes the whole document invalid, so fix the first reported error and try again.
- Everything runs in your browser, so you can use XML Formatter even on a slow connection once the page has loaded.
Limits to keep in mind
- The tool works on the text you paste and does not check it against a schema. Always test the output in your own project.
