title: Read VBA macros (or vbaProject.bin) of an Excel file without opening it in MS Excel
body: <p>I would like to analyze Excel files, especially those which contain VBA programs inside. because I plan to run this analysis on lots of Excel files one by one, I don't want to open these files within Microsoft Excel to analyze them.</p>
  
  <p>One difficulty is to find and parse the VBA macros of an Excel file. We know that an Excel file can be converted to <code>.zip</code> file which contains lots of <code>.xml</code> and <code>vbaProject.bin</code>, it is pretty certain that VBA macros are in <code>vbaProject.bin</code>. However, the problem is how to read it?</p>
  
  <p>Does anyone know if there is any tool or API to find and parse the VBA macros?</p>
