Just as the poll asks do you use macros in Microsoft Office, Excel not included. I simply ask because I've been working with the software for decades and never used it or came across someone who used it. I always assumed it was strange backend stuff. While I've never seen someone use macros in Excel, the mathematical nature of the software I think would lend it self better than an application such as Word.
If you vote 'Yes' please explain how you use it.
