🚀 go-pugleaf

I'm looking for an application, perhaps a DA, that will convert text
that is in all upper case to lower case.  MS Word will convert selected
lower case text to uppercase, but apparently not the reverse.  My
specific problem is that I'd like to import a bibliography list I have
generated from our libraries link to Current Contents into EndNote, and
I'd like to clean up the problem with CC citations containing all upper
case letters.  In the best of all possible worlds, the program would
leave the first letter of each word capitalized, such as in the
following example:

			ABCDEFG -> Abcdefg

This will leave authors names capitalized.  I will certainly have to do
some re-editing of the files, but this program will probably minimize
the effort.

This is probably a question that has been asked before, so please send
your responses directly to me.  Thanks.
