I\'m writing to Excel file using OLEDB (C#). What I need is just RAW data format.
I\'ve noticed all cells (headers and values) are prefixed by apostrophe (\')
<
Insert some dummy values for the columns which has apostrophe attached in the template file. Say for example for Name column put something like this dummyname, and age column put 99. Instead of inserting a new row in the template just update the row (Update..... where Name = 'dummyname' and age =99).
This has worked for me..
Hope it works for you also!
