title: Unmerge in Google Apps Script
body: <p>I'd like to unmerge all the cells of my google spreadsheet using script. I believe that VBA has this option (cells.unmerge) but I can't find a similar operation in GAS. I've tried this script but it didn't seem to work.</p>
  
  <pre><code>function MyFunction() {
  var Sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var Range = Sheet.getDataRange().activate();
  Range.clearFormat();
  }
  </code></pre>
