Hi Chris,
You can use Filtering to delete duplicate based on one column,
you would have to use a helper column to use filtering and not use a macro.
Filter Unique Records

You might also look at Chip Pearson's page on duplicates
subtopic -- Tagging Duplicates
http://www.cpearson.com/excel/duplic...gingDuplicates

and two video presentations on duplicates as an explanation of formulas at

I have an excel spreadsheet with over 19,000 contacts. Some are duplicates
(Contact) and I would like delete them.
The columns across the top are as follows:
Company/Contact/Phone1/Zip/Address/City/Acct Manager/Record Type

Can someone please write a macro, or tell me how to delete the duplicates
for Column B?
