Yes, logical functions can test for conditions.
A logical or boolean function is one that works with logical or boolean values - values that can only be either true, or false.

A logical function is one that can return a true value or a false value. They are usually used in doing comparisons and seeing if things are equal to each other or not, or which is higher or lower. The logical functions that Excel provides are: TRUE FALSE AND OR NOT IF
Logical functions like IF functions or others can be used.
They are organised into categories. Those categories are: Database functions Date and time functions Engineering functions Financial functions Information functions Logical functions Lookup and reference functions Math and trigonometry functions Statistical functions Text functions External functions Cube functions
IF function
Logical functions, such as IF, AND & OR.
They are logical functions, the most common one being the IF function.
The different functions from the Logical functions category deal with true and false. The main one of them is the IF function.
