Sort Email List Out Help

Right, I've just got an email list using a nice harvester the only problem is it's jumbled and has a lot of CL emails in there which I don't want.

Is there a program that can sort it? Either Alphabetically or another way?

Thanks

What is the format like.

Should be able to do somthing with a regex (I always use PHP for this) or even Excel.

However would need a better look at the data before I could give you somthing useable.
