I have a very large SS with multiple worksheets. I need to make some changes
but don't want to effect Macros or other formulas.

If A1 has a value of 2 and
B1 has a value of 3 and
C1 has a formula of A1+B1

Is there a function or command I can use on A1 that will show me that it is
included in a formula in C1?
