title: How can I insert a character into a string? (VBA)
body: <p>I have a column of product numbers that are all formatted like this:</p>
  
  <pre><code>MK444LLA
  </code></pre>
  
  <p>...same number and letter pattern, same character count. I need to insert a <code>/</code> into each cell so they all end up like this: </p>
  
  <pre><code>MK444LL/A
  </code></pre>
  
  <p>I'm thinking I just need a solution for the first row, which I can then apply to the entire column.</p>
