What is Format XML?

Format XML is a free online XML formatter and beautifier. Paste any raw or minified XML and get it back with proper indentation, making it easy to read and debug. Also minifies XML by removing all whitespace.

How It Works

The tool uses the browser's built-in DOMParser to parse the XML. If parsing succeeds, it recursively walks the DOM tree and rebuilds the XML string with 2-space indentation. Minification strips all text nodes that are only whitespace.

How to Use

  1. 1

    Paste your XML

    Paste raw or minified XML into the input editor.

  2. 2

    Format

    Click "Format XML" to indent the markup with proper nesting and line breaks.

  3. 3

    Validate

    The tool checks for well-formedness errors and highlights any issues with the tag structure.

  4. 4

    Copy or download

    Copy the formatted XML to your clipboard or save it as a .xml file.
