This has nothing to do with BJ, but need a little help from someone with Excel and/or MSWord experience.

I have several txt files with a list of "words" (mixed numbers/letters), one per line.
I want to import several of these txt files into Excel (or Word) and do a compare to find the "words" that are common to more than one file.
Can someone tell me if this is possible, and if so, how to do it?
Thanks.
