Unfortunately, the maximum number of nested
IF statements in Excel is 64. When you add another level to your formula, it exceeds this limit and you get the error message you mentioned.
One solution to this problem is to use the
CHOOSE function instead of nested
IF statements. The
CHOOSE function allows you to select a value from a list of options based on a numeric index.
Here's an example of how you could use the
CHOOSE function to replace your nested
IF statements:
- =CHOOSE(A1,M1,N1,O1,P1,Q1,R1,S1,T1,U1,U2,U3,U4,U5, U6,U7,U8,U9,U10)
In this formula, the first argument (
A1) is the numeric index that determines which value to select. The remaining arguments are the list of options to choose from.
This formula is much simpler and easier to read than the nested
IF statements, and it doesn't have the same limitation on the number of levels.
