title: Is csv with multi tabs/sheet possible?
body: <p>I am calling a web service and the data from the web service is in csv format. 
  If I try to save data in xls/xlsx, then I get multiple sheets in a workbook.
  So, how can I save the data in csv with multipletab/sheets in c#.</p>
  
  <p>I know csv with multiple tabs is not practical, but is there any damn way or any library to save data in csv with multiple tabs/sheet?</p>
