title: Driving Excel from Python in Windows
body: <p>We have various spreadsheets that employ deliciously complicated macros and third party extensions to produce complicated models.  I'm working on a project that involves slightly tweaking various inputs and seeing the results.  Rather than doing this by hand or writing VBA, I'd like to see if I can write a python script to drive this. In other words, the python script will start up, load the excel sheet, and then interact with the sheet by making minor changes in some cells and seeing how they affect other cells.</p>
  
  <p>So, my question is twofold:</p>
  
  <ul>
  <li><p>What is the best library to use to drive excel from python in such fashion?</p></li>
  <li><p>Where's the best documentation/examples on using said library?</p></li>
  </ul>
  
  <p>Cheers,
