This XML Formatter tool helps you beautify and format XML data with proper indentation and structure. It makes XML code more readable and easier to understand by organizing elements hierarchically.

How to use: Paste your XML code below, select formatting options, and click “Format XML” to beautify or “Minify” to compress. Errors will be shown if XML is invalid.

Paste your XML code:

<div class="indent-option">
        <label for="indentSize">Indent Size:</label>
