title: How can I share repeated code in multiple Excel files?
body: <p>I started maintaining a huge number of <strong>Excel tools</strong> and I'm noticing that many of them have the same code, simply copy-pasted and then reused at the occurrence. </p>
  
  <p>Since I would prefer to avoid copy-pasting the same code over and over, I was wondering: is there a way to refactor this code into a shared library?</p>
  
  <p><strong>Edit</strong>:
  Please take into account that we don't have admin rights (so we cannot put files into <code>C:\Windows</code> folder) and there is only one person that can modify the code, while the others only execute it.</p>
