I am drawing an rdlc report which I am saving to Local folder though my code as Excel file. Now I want to convert this file into CSV. But as my columns are dynamic in rdlc there gets inserted some blank or empty columns i.e zero width column. As a result after converting the Excel to CSV there also gets inserted a blank or empty column. In the CSV it inserts a comma for a blank. So any way how to delete empty column with no header or blank column...
