XML Formatter & Beautifier
Beautify or minify XML with proper indentation, validated in-browser.
Formatted XML will appear here.
Paste messy XML to pretty-print it with consistent indentation, or minify it to a single line. The browser's XML parser checks that your document is well-formed and reports the first error if not. Everything runs locally — your data never leaves the page.
How to use the XML Formatter
- Paste your XML into the input box.
- Choose an indent size, then click Beautify or Minify.
- If the XML is malformed, read the error and fix it.
- Copy the formatted output.
Frequently asked questions
Does it validate against a schema?
It checks well-formedness (correct nesting and syntax), not validity against a DTD or XSD schema. Most formatting errors are well-formedness issues.
Is my XML sent anywhere?
No. Parsing and formatting run entirely in your browser.
