title: Parsing Excel Binary Workbook file?
body: <p>I am having a heavy excel workbook with many sheets and loads of data and formulas and the file has a extension of <code>xlsb</code> (Excel Binary Workbook files store information in binary format ).  I am currently using <a href="http://roo.rubyforge.org/" rel="nofollow">roo</a> in my application to parse <code>xlsx</code> which works fine. </p>
  
  <p>Any suggestions how can i parse this <code>xlsb</code> without converting it into a CSV or xlsx</p>
