title: Load xlsx file from drive in colaboratory
body: <p>How can I import MS-excel(.xlsx) file from google drive into colaboratory?</p>
  
  <pre><code>excel_file = drive.CreateFile({'id':'some id'})
  </code></pre>
  
  <p>does work(<code>drive</code> is a <code>pydrive.drive.GoogleDrive</code> object). But, </p>
  
  <pre><code>print excel_file.FetchContent()
  </code></pre>
  
  <p>returns None. And</p>
  
  <pre><code>excel_file.content()
  </code></pre>
  
  <p>throws:</p>
  
  <blockquote>
    <p>TypeErrorTraceback (most recent call last)
     in ()
    ----> 1 excel_file.content()</p>
    
    <p>TypeError: '_io.BytesIO' object is not callable</p>
  </blockquote>
  
  <p>My intent is (given some valid file 'id') to import it as an io object, which could be read by pandas <code>read_excel()</code>, and finally get a pandas dataframe out of it.</p>
