How to nest more than 7 IF functions

 IF_NESTED_2 A well known limitation to Excel is that you cannot "nest" more than 7 functions. For example, the following formula will FAIL because the limit is exceeded. =IF(Sheet1!\$A\$4=1,11,IF(Sheet1!\$A\$4=2,22,IF(Sheet1!\$A\$4=3,33, IF(Sheet1!\$A\$4=4,44,IF(Sheet1!\$A\$4=5,55,IF(Sheet1!\$A\$4=4,44, IF(Sheet1!\$A\$4=5,55,IF(Sheet1!\$A\$4=6,66,IF(\$A\$4=7,77,FALSE)))))))) As a general "rule of thumb," if you have a formula with more than 7 nested statements, you should consider using a VBA function instead. However, if you do not want to use VBA, you can get around this limitation by creating a defined name that refers to part of the formula. Since defined formulas are evaluated separately, you can have one or more defined formulas which refer to large formulas, and combine these into a "master" formula. Suppose we wanted an nested IF formula to test: IF A4 = 1 Then 11 Else If A4 = 2 Then 22 Else If A4 = 3 Then 33 Else If A4 = 4 Then 44 ... Else If A4 = 13 Then 130 Else "Not Found" and so on. Of course, as a practical matter, we'd be better off using a VLOOKUP to do this, but this will work for illustration. First, we'd create a named formula called OneToSix, referring to the formula: =IF(Sheet1!\$A\$4=1,11,IF(Sheet1!\$A\$4=2,22,IF(Sheet1!\$A\$4=3,33,IF(Sheet1!\$A\$4=4,44,IF(Sheet1!\$A\$4=5,55,IF(Sheet1!\$A\$4=4,44,IF(Sheet1!\$A\$4=5,55,IF(Sheet1!\$A\$4=6,66,FALSE)))))))) Then create another named formula called SevenToThirteen, referring to the formula: =IF(Sheet1!\$A\$4=7,77,IF(Sheet1!\$A\$4=8,88,IF(Sheet1!\$A\$4=9,99,IF(Sheet1!\$A\$4=10,100,IF(Sheet1!\$A\$4=11,110,IF(Sheet1!\$A\$4=12,120,IF(Sheet1!\$A\$4=13,130,"NotFound"))))))) Finally, enter the "master" formula in the worksheet cell: =IF(OneToSix,OneToSix,SevenToThirteen) This "beats" the nested function limitation because no single part of the formula exceeds the limit, even though the "sum" of the components do. You can use this technique whenever you exceed the limit on nested functions.
