title: Export to excel opening it
body: <p>I currently have an option in my app to export to Excel. It saves the data to a file in disk. </p>
  
  <p>I would like to open Excel instead and show the data. Do any of you know if this is possible and how to accomplish it?</p>
  
  <p>I guess I can just open the file I'm already saving to disk, but it would be just better to not save a file to disk at all.</p>
