title: Open Excel xlsx file for viewing
body: <p>I need to open up an xlsx file so that the user can see it.
  <br>I used the following code but was not able to display the excel file:</p>
  
  <pre><code>public ActionResult GetExcelReport()
  {
      string fileName = "Sheet1.xlsx";
      string path = Path.Combine(@"C:\Test", fileName);
  
      return File(path, "application/xlsx");
  }
  </code></pre>
  
  <p>I was hoping that the retrun <code>File(path ...</code>
  <br>would actually open up the file for viewing. </p>
