title: Best way to do Version Control for MS Excel
body: <p>What version control systems have you used with MS Excel (2003/2007)? What would you recommend and Why? What limitations have you found with your top rated version control system?</p>
  
  <p>To put this in perspective, here are a couple of use cases:</p>
  
  <ol>
  <li>version control for VBA modules </li>
  <li>more than one person is working on a Excel spreadsheet and they may be making changes to the same worksheet, which they want to merge and integrate. This worksheet may have formulae, data, charts etc</li>
  <li>the users are not too technical and the fewer version control systems used the better</li>
  <li>Space constraint is a consideration. Ideally only incremental changes are saved rather than the entire Excel spreadsheet.   </li>
  </ol>
