How can I delete duplicate imported products?

Hello,

I've somehow got duplicate products (a bunch of them) after uploading about 4000 new items yesterday. My spreadsheet didn't have duplicates so I'm not sure how it happened but I'm sure I did something wrong. It's easy to spot them when I'm working in the admin/category section as the extra items do not have a model number. I can also export a database and the extras are listed in it, again easy to spot as they do not have model numbers.

I'm working in the admin this morning trying to delete them one by one, is there an easier way to clean this up? I use Apsona for uploading and downloading but haven't used it for anything else so I don't know if it would help or not.

Thanks for any information anyone has,

Jim

Please disregard the above post, I figured out how to delete those extra items using Apsona, worked great and only took a couple minutes.
