  <p>Is there a way to quickly identify or create a simple marco to identify cells that doesn't have a formula?</p>
  
  <pre><code>--------------------------------
  |=A1*1 |   151 | =A3*1 | =A4*1 |
  --------------------------------
  |=B1*1 | =B2*1 |   100 | =B4*1 | 
  --------------------------------
  </code></pre>
