title: Select all cells with data
body: <p>I have some data in an Excel Worksheet. I would like to select all the cells which contain data.</p>
  
  <p>For example, for a worksheet with data in cells A1, A2, A3, B1, B2, B3, C1, C2, and C3, how can I select just this 3x3 grid, and not the entire sheet?</p>
  
  <p>I am looking for something like <code>ActiveSheet.SelectUsedCells</code>.</p>
