Sometimes you use Excel, sometimes you use Google Sheets
The custom formula for conditional formating a cell (E2) with a date that has passed is
=E2<today()
The formula if you don’t want blank cells marked is
=and(E2<today(), not(isblank(E2)))
And the formula to not affect cells if there’s data in a specifik other cell (A2) is
=and(E2<today(), not(isblank(E2)) , isblank(A2) )
So, list of due date in column E, red marked if passed dates, if done there should be a comment in A2 and therefor don’t format those with a comment there.
