title: C#/.Net Create Excel File From XML
body: <p>I have seen a working example in past where some data/xml data was created. However it was saved with .xls extension. So when we open it, it was an excel file. </p>
  
  <p>I don't remember how the xml tags were formed or what they were. I've searched and looked around but haven't succeeded yet. </p>
  
  <p>I don't want to use any library, either one free from microsoft or open source or any other third party one, to do this thing. </p>
  
  <p>Anyone has any idea about acomplishing this ?</p>
