body: <p>Is it possible to convert a .csv file to .xlsb programatically ?
  (Preferrably C#)</p>
  
  <p><a href="https://stackoverflow.com/questions/6442698/convert-xls-to-xlsb-programatically">Convert XLS to XLSB Programatically?</a></p>
  
  <p>shows how to convert XLS to XLSB ,  can I use the same to convert it from.csv? Won't there be any formatting issues?
  I am doing this on the server side because the .xlsb file size is very small compared to a .csv file, and I don't have an option of zipping my file.</p>
