title: Will I require MS Excel installed on the server if I am generating Excel file using NetOffice?
body: <p>I am trying out both <strong>NetOffice</strong> and <strong>NPOI</strong> for to use in an ASP.NET project. </p>
  
  <p>I am making an ASP.NET web site where on click of a button, I want to <strong>generate</strong> an Excel file in a <strong>password protected</strong> state and send it to the client to download it. </p>
  
  <p>But I want to know whether, <strong>will I require MS Excel installed on the server?</strong> 
  OR Is there a way where I can make this work on a server where MS Excel is <strong>NOT</strong> installed? </p>
  
  <p>Also what are other pre-requisites for both these APIS? </p>
  
  <p>I basically have to identify which of these APIs will work for me in a server without Microsoft Excel installed in it.</p>
