title: Convert CSV into XLS
body: <p>I'm working in a web application separated in blocks and I'm getting a CSV object from a work mate of mine which I must convert into XLS to be passed into an Excel Processor they built.
  This CSV object is delimited by the character ";".</p>
  
  <p>What I'd like to know is how I can convert the CSV object into XLS programatically.</p>
