How do I avoid duplicating names in excel?

B

Brian,WI

I'm collecting business cards to enter contact information in MS Excel. I
will probably be collecting the same cards, month after month. Is there a way
that when I start entering data from a business card, Excel will know that
infomation is already entered so there won't be a duplicate enteries of the
same contact?

Excel is what I need to use so please don't bring up Access if that was an
option.

Thanks.
