I’ve run into a similar situation before when I was trying to clarify some data in a project. Unfortunately, Excel doesn’t let you link one note to multiple cells directly, but I found a workaround that might help. You can create a separate cell to hold your note and reference that cell in the comments of the others. That way, you can have all your explanations in one spot. Also, if you're looking for better organization, I discovered some
free Excel template online that could help set things up more clearly. They’ve been a lifesaver for keeping my projects tidy! Keep experimenting, and you'll figure it out.
