title: How to convert *.xlsb to array or *.csv using php
body: <p>I am trying to convert <code>*.xlsb</code> file into <code>php array</code> or <code>*.csv</code> file (or at least <code>*.xls</code>). I tried to use <code>PHPExcel</code>, but looks like it can not recognize what's inside this file.</p>
  
  <p>I noticed, that you can rename <code>*.xlsb</code> file into <code>*.zip</code> file and then unzip it using command line <code>unzip *.zip</code>. And after this you will get next folders with <code>sheet1.bin</code> file:</p>

  <p>Looks like this file should contain Excel cell values, but I still can not parse it using <code>PHPExcel</code>. Can someone help me is it even possible to parse <code>*.xlsb</code> files and get information from it? Or maybe it is possible to parse this <code>sheet1.bin</code> file?</p>
