Create conditional formulas

Testing whether conditions are true or false and making logical comparisons between expressions are common to many tasks. You can use the AND, OR, NOT, and IF function to create conditional formulas.

The IF function uses the following arguments.

Formula with the IF function

Formula with the IF function
Callout 1 logical_test: The condition that you want to check.
Callout 2 value_if_true: The value to return if the condition is true.
Callout 3 value_if_false: The value to return if the condition is false.

What do you want to do?

Create a conditional formula that results in a logical value (TRUE or FALSE)

Create a conditional formula that results in another calculation or in values other than TRUE or FALSE


Create a conditional formula that results in a logical value (TRUE or FALSE)

To do this task, use the AND, OR, and NOT functions, and operators (operator: A sign or symbol that specifies the type of calculation to perform within an expression. There are mathematical, comparison, logical, and reference operators.).

=AND(A2>A3, A2<A4) Is 15 greater than 9 and less than 8? (FALSE)
=OR(A2>A3, A2<A4) Is 15 greater than 9 or less than 8? (TRUE)
=NOT(A2+A3=24) Is 15 plus 9 not equal to 24? (FALSE)
=NOT(A5="Sprockets") Is A5 not equal to "Sprockets"? (FALSE)
