If you ever have to search for and replace the same text in
multiple Word documents—after changing your phone number, for
example—Australian export WordPipe 3.4 ($129) is the program you're
looking for. This utility lets you define a word or phrase to find
and a word or phrase to replace it with. It then applies the change
to all the files in a given folder and optionally all subfolders.
The program calls on Word to do the actual search and replace, with
options to match cases, search inside fields (including hyperlinks),
search for whole words only, and more.
