What is the Free XML Formatter?

The free XML Formatter beautifies any XML document into properly indented, readable markup in seconds. Paste your raw or minified XML into the Input textarea, choose Format to add indentation or Minify to strip all whitespace, and get clean output instantly. The tool validates your XML at the same time — catching unclosed tags, mismatched elements, and encoding errors using the browser's native XML parser.

→ Format XML API responses (SOAP, RSS, Atom, Sitemap XML) for easier reading
→ Minify XML config files and data feeds before deployment
→ Validate XML structure when debugging integrations or data imports
→ Clean up XML exported from Microsoft Office, databases, or CMS platforms
→ Inspect and format SVG or HTML files that are XML-based

How to Use the Free XML Formatter

1 Paste your XML into the Input textarea.
2 Choose Format to pretty-print with indentation, or Minify to collapse it to a single line.
3 If your XML contains errors, a red validation message appears below the input with a description of the problem (unclosed tag, unexpected character, etc.).
4 Once valid, the formatted XML appears in the Output panel.
5 Click Copy to copy the result to your clipboard, or Download to save it as a .xml file.
