hamking01,
I've read your posts in other threads. Several people have asked what it is you are trying to do. You haven't answered this question yet.
In your original post, you say you want to replace "blank" cells with "" (null cells). Now you want to replace null cells with " " (which is not an empty cell). I haven't used ASP.net, but I have imported lots of Excel files into Access. Why do you want no empty cells? Do you want the entire worksheet to have no empty cells?
If you back up and ask for advice on how to get your end results instead of trying to solve one baby step of a process at a time, chances are someone here can help you figure out how to proceed.
