title: Remove the save file dialog when exporting Excel with filesave js
body: <p>My goal is auto generating excel files when the time comes to 12:00. But when invoke saveAs in Filesaver.min.js, it will prompt a Save File dialog, i try to debug and remove the "OpenFileWindow" but failed.</p>

  <p>Another question is why there is a Click "Mouse Event" in Filesaver.min.js, which is for openning the dialog?</p>
  
  <pre><code> var t=new MouseEvent("click");
      e.dispatchEvent(t)
  </code></pre>
  
  <p>Thanks a lot!</p>
