I've used it for designing never ending platformer game. An excel file determines zones where the next platform can be generated relative to the end of the current one. Blue cell is the current platforms end, green cells are easy places to jump to, yellow medium, red are hard. Makes it very easy to adjust difficulty. Want hard mode harder? Reduce the amount of red squares to only the hardest jumps. Want it easier? Colour some of the yellows in red. Etc.
