title: Change text effects in PowerPoint
body: <p>I want to change text effects in PowerPoint, specifically Glow effect.</p>
  
  <p>I have about ~2500 PowerPoint files with 1-15 slides in each, and I need to change the text to have a text glow effect (not shape glow effect).</p>
  
  <p>I thought the easiest approach would be to create a macro, however I couldn't find a way to do this.</p>
