title: Split string by delimiter and transpose value(s) vertically
body: <p>I have a column in excel separated by commas (,)</p>
  
  <pre><code>       column  
  cell1:  1,2,3
  cell2:   2,4
  </code></pre>
  
  <p>I want to split each cell so that values appear in vertical cell so that each is converted to </p>
  
  <pre><code>cell1 =&gt; split into 3 vertical cells containing values 1,2,3 
  cell2 =&gt; split into 2 vertical cells containing values 2,4 
  </code></pre>
  
  <p>I  found many ways to do this horizontally, but struggling splitting over vertical cells.</p>
