Perhaps you don't mean CVS, but CSV (Comma Separated Variables)?
Yours is another of those posts which expects a certain clairvoyant ability
from readers of this group. You say "I could not able to", but if you want
us to help, you will have to give us a better idea of what the failure
symptoms are. What error message are you receiving? Did it produce a CSV
file? If so, did you look at the CSV text tile with a text editor (such as
Notepad) to see what was in it? If so, how did the contents differ from
what you were expecting?
