title: How to run VBA code from external file?
body: <p>I have an excel file with VBA scripts in its background.</p>
  
  <p>I also have an external file generated in a separate process that contains VBA functions i need to integrate into the main Excel.</p>
  
  <p>Today, I copy-n-paste the external functions into the excel editor manually.</p>
  
  <p>I wonder if there is a way to <code>include</code> or <code>import</code> the external functions without me copy-n-paste them.</p>
