title: Create Powerpoint with JavaScript
body: <p>JavaScript cannot create files locally on the clients filesystem. However, I am wondering, if it is possible to somehow create a Powerpoint MIME in a web page (a div or a iframe) from some JSON and then let the UserAgent figure out it is Powerpoint in the expectation that the UserAgent will offer the user the choice to display it as a powerpoint presentation? </p>
  
  <p>Note: The idea here is to be able to take some JSON and make a powerpoint presentation without having to make a request to a Server to create a Powerpoint file.</p>
