title: Remove non-numeric characters from a range of cells
body: <ol>
  <li>I have a 1500 row excel file. </li>
  <li>In the first column I have characters mixed up with numbers (every row is different).</li>
  <li>I would like to leave only the numbers and delete the alpha characters.</li>
  </ol>
  
  <p>For example in <code>A1</code> I have   </p>
  
  <blockquote>
    <p><strong>f90f5j49,35.48</strong>  </p>
  </blockquote>
  
  <p>and after I delete the alpha characters it should be  </p>
  
  <blockquote>
    <p><strong>905493548</strong></p>
  </blockquote>
  
  <p>What is the best way to do this?</p>
