title: Excel Workbook Open event from within an addin?
body: <p>I am trying to trigger a macro to run when an Excel document is opened. </p>
  
  <p>The problem I am running into is that all of my code resides within an Excel add-in. The Workbook_Open event doesn't work because I can't put the code in individual documents, I need it to reside in the add-in and run whenever any document is opened.</p>
  
  <p>Is there a way to modify the Workbook_Open event or is there another way to trigger a macro when a different document is opened?</p>
