  <p>Let's say I have a <code>Fullname</code> field that looks like so:</p>
  
  <pre><code>Gordon, Liza
  Shiksa, Nancy
  Shkura, Lola
  Sukovich, Matthew
  </code></pre>
  
  <p><strong>How would I extract last name?</strong></p>
  
  <p>My desired output would look like this:</p>
  
  <pre><code>Gordon
  Shiksa
  Shkura
  Sukovich
  </code></pre>
