Winning Numbers and Tic-Tac-Toe Workouts

I have a question and anyone here can answer: I am intrigued by these tic-tac-toe workouts, but often the winning numbers don't follow a pattern, such as diagonal, or corners, but can come from anywhere on the grid. Is there a formula that can be used to determine all possible P3 and P4 numbers from a tic-tac-toe workout, or better yet, can this be done on excel or some computer program? I am tired of missing winning numbers because of misreading these workouts
