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>
        <select id="indentSize" class="form-control">
          <option value="2">2 spaces</option>
