title: How to download excel file
body: <p>I am working with the GUI where there is a button. On button click, an ajax call happens which returns a JSON to the backend in Django's view.py. On the basis of the JSON, I am creating an excel file and the path of this file is returned to the place where ajax call happened. I want that file to download on the click of the same button.</p>
  
  <p>i.e, is it possible to do all these operations (from ajax call to download the excel file) with one click of that button?</p>
  
  <p><code>edit</code></p>
  
  <p>Path means the physical path of file system.</p>
