title: Laravel Excel: how to get value of a cell?
body: <p>I've loaded <code>.xls</code> file with <a href="https://github.com/Maatwebsite/Laravel-Excel" rel="nofollow">Laravel Excel</a>:</p>
  
  <pre><code>Excel::load('public/files/20160621.xls', function($reader) {
      // read a cell value
  });
  </code></pre>
  
  <p>How do I read values of cells of the loaded excel file? Documentation seems to be unclear on that part.</p>
