Expiration Notification in Excel
 

Hello All,

I need some help setting up a notification in Excel. My company wants me to
put all of our certifications in their MS Excel spreadsheet and when one
employee's cert is about to expire, within a few months, to open a
notification or play a sound, something automatic so it's not something we
have to monitor constantly. I know you can do this in Calendar functions,
conditional formatting, and even a little easier in a DB but they are
specific about using Excel. Any and all help would be extremely appreciated!
Thanks.
