AND function

The AND function in Excel is a logical function that returns TRUE if all of its arguments are TRUE, and FALSE if at least one of them is FALSE. It’s like a digital gate that only opens when all the switches are on.


AND(logical1, [logical2], …)


logical1:The first condition or expression that you want to test.
[logical2]:(Optional) Additional conditions or expressions that you want to test. You can include up to 255 of these.

How to Use

The AND function is quite straightforward. It takes one or more logical expressions and checks if they are all TRUE. If they are, it returns TRUE; otherwise, it returns FALSE. Let’s look at some examples to understand better:

Example 1: Checking if two conditions are met:

This formula returns TRUE only if the value in cell A1 is greater than 5 and the value in cell B1 is less than 10.

Example 2: Using more than two conditions:

This formula returns TRUE only if all three conditions are met simultaneously: C1 contains “Yes,” D1 contains “OK,” and the value in cell E1 is less than 100.

Example 3: Combining with other functions:

Here, the AND function is used within an IF function to determine whether two conditions are met. If both conditions are TRUE, it returns “Valid”; otherwise, it returns “Not Valid.”

Remember that the AND function requires all conditions to be TRUE to return TRUE. If any of the conditions are FALSE, it returns FALSE.
