📑 XML Formatter
Format and beautify XML. Indent elements, normalize whitespace, and validate syntax — all in your browser, no upload, instant results.
About the XML Formatter
This XML formatter runs entirely in your browser. Paste your XML content into the input box, choose an indentation style, and click Format to get beautifully indented output. You can also minify XML to remove all whitespace, or validate to check for syntax errors. Nothing is uploaded to a server — all processing happens locally with the browser's built-in DOMParser.
Features
- Format — Pretty-prints XML with consistent indentation (2 spaces, 4 spaces, or tab).
- Minify — Removes all unnecessary whitespace between tags to reduce file size.
- Validate — Checks the XML for syntax errors and reports the issue if any.
- Preserves content — Text content, CDATA sections, and attributes are kept intact.
How to use
- Paste your XML content in the input box.
- Choose your preferred indentation style.
- Click Format, Minify, or Validate as needed.
- Click Copy to copy the result, or Clear to start over.
Frequently asked questions
Does this tool upload my XML? No. All formatting happens locally in your browser. Your data never leaves your device.
What's the difference between Format and Minify? Format adds indentation and line breaks for readability. Minify removes all whitespace between tags to make the file as small as possible.
What does Validate do? It tries to parse your XML and reports whether it's well-formed. If there's a syntax error, you'll see the error message.
Are comments preserved? Yes, comments are kept in the formatted output. They are stripped only from the minified output where appropriate.
