deleting duplicate data
 

I have a set of labels that I exported from my computer at work. They are
formated as standard mailing lables 1" x 2 5/8". The information shows up in
excel as follows.
uses 3 columns - A, C & D. Each column represents a lable on a 3 columns
per row lable sheet. Rows in excel, 1 is name, row 2 is street address and
row 3 is city , state and zip. each 5 rows after repeat, example row 6 name,
7 address, 8 city, state, etc.
The problem I am having is there are a lot of duplicate address and I am
trying to delete them and then reformat the output so that I dont have a
bunch of blank labels after printing.
I don't know if this can be done in excel of if it would be better to
somehow export the information into a text file and then cycle it into a
Access and use the features there. Thanks for any help you can give
