If you want to check the value in one cell if it is blank or empty cell, then you can use IF function in combination with ISBLANK function or logical operator (equal to) in excel.

Excel IF function check if the cell is blank

Let’s see the generic IF formula with ISBLANK function and Logical operator = as follows:

=IF(ISBLANK(B1),"PASS","FAILED")
=IF(B1="","PASS","FAILED")

In the above two IF formulas, it will return “PASS” if Cell B1 is blank, Otherwise returns “FAILED”.

Excel IF function check if the cell is non-blank

If you want to check the value in one cell if it is not blank or not empty cell, then you can use IF function in combination with ISBLANK function or logical operator (not equal to) in excel.

let’s see the generic IF formula with ISBLANK function and Logical operator <> as follows:

=IF(ISBLANK(B1)=FALSE,"PASS","FAILED")
=IF(B1<>"","PASS","FAILED")

In the above two IF formulas, it will return “PASS” if Cell B1 is not blank, otherwise returns “FAILED”.

Let’s write a nested if function in combining with AND function and ISBLANK function to achieve the following test criteria.

IF cell A1 is greater than or equal to 10, then add to C1.

If Cell B1 is greather than or equal to 10, then subtract from C1.

If both A1 and b1 are blank cells, then equals to C1.

Based on the above logic, we can write down the following excel nested if formula (statement):

=IF(A1>=0,C1+A1, IF(B1>=0,C1-B1, IF(AND(ISBLANK(A1)=TRUE, ISBLANK(B1)=TRUE),C1,"")))
