If you have a million lines, you must be using Excel 2007. So,
highlight your data, click Insert, then Table. Your data will be a
table, and it will have some nice formatting. The click on Table
Tools; then Remove duplicates will be an option. After you pick that
you will have a form to allow you to select what columns must match to
constitute a "duplicate". Then click okay, and the duplicates will be
gone.

Good luck.
