So I've always struggled to understand how sheets are put together. I can't remember how all the formulas and cells link together and where the calculations come from. So I thought I'd have a look and see what tools are out there and found this tool called Slate. It visualises how all the cells in a sheet link together and makes it really easy to understand. I'm sure other people have this problem so I thought I'd share it here.
