I think Advanced filter should work for you.
Follow these steps-

1. Select the entire range, say A1:A4500, including column heading
2. Go to Data--Filter--Advanced filter
3. Select copy to another location
4. Tick the check box 'Unique Records only'
5. Specify the location where you want the unique records to be listed.

Remember step 4 and 5 are most important.

Hi,

I've been trying for several hours to delete duplicates from an Excel file
that has been exported from a database application. I have read many, many
posts, and none seem to work for me. I've tried conditional formatting to
highlight duplicates, Advanced Filtering (many times), and it just doesn't
seem to work. I am trying to remove duplicates based on e-mail addresses,
from a table of 4500 records. Can someone please tell me step-by-step what
to do: where to click, the terms that Excel uses etc?

Thanks,

Jane
