Depending on what you're doing, you may be able to loop through each comment and
change the formats.

I'd record a macro when I did one alteration, then try to generalize it to do
all the comments.

Debra Dalgleish has lots of sample code for working with comments:

I'd like to change the formatting of all comments in an Excel worksheet. The
help menu only tells how to format individual comments. Does anyone know a
simple way to do this? (Using format painter might be an option if there are
only a few comments, but I don't think it would work very well when more than
100 cells have comments.)
Thanks for any help on this.
