title: VBA VS. VSTO what is the difference, should I upgrade?
body: <p>I am a huge fan of the KISS principle (Keep it simple) and a long time VBA for excel user. However all the articles I can find on VBA vs. VSTO (Visual Studio Tools for Office) seem very complicated. </p>
  
  <p>Firstly, I am sick of the very poor IDE built into Excel and I am looking for a new one. VSTO using Visual Studio as the IDE seems to be the only alternative.</p>
  
  <p>So I seek to understand what is the difference between VBA and VSTO to know if it is worth me learning to use VSTO? </p>
