title: How can I strip macros from an Excel workbook?
body: <p>I am currently forced to use Office Live / Skydrive (whatever the proper name is) to edit Excel workbooks. Skydrive won't let me upload a workbook that contains macros, and I don't need the macros, so I would like to write a little cleansing app in C# that simply removes all macros. How can I go about this using Excel 2007 and above (.xlsm) documents?</p>
  
  <p><strong>EDIT:</strong>  Basically, I would like to open an xlsm document and save it as an xlsx document, without required Excel to be installed, i.e. via the OpenXML SDK or something.</p>
