NOT in Excel

NOT in Excel

NOT function is an inbuilt function that is categorized under the Logical Function; the logical function operates under a logical test. It is also called Boolean logic or function. Boolean functions are most commonly used along with or in conjunction with other functions, specifically along with conditional test functions (“IF’’ FUNCTION), to create formulas that can evaluate multiple parameters or criteria and produce desired results depending on that criteria. It is used as an individual function or part of the formula and other excel functions in a cell. E.G. with AND, IF & OR function. It returns the opposite value of a given logical value in the formula, NOT function is used to reverse a logical value. If the argument is FALSE, then TRUE is returned and vice versa.

Note: Use NOT function when you want to make sure a value is not equal to one Specific or particular value

It’s a worksheet function; it is also used as part of the formula in a cell along with other excel function

• If given with the value TRUE, the Not function returns FALSE
• If given with the value FALSE, the Not function returns TRUE

NOT Formula in Excel

Below is the NOT Formula in excel:

=NOT (logical) logical – A value that can be evaluated to TRUE or FALSE

The only parameter in the NOT function is a logical value.

The logical test or argument can be either entered directly, or it can be entered as a reference to a cell that contains a logical value, and it always returns the Boolean value (“TRUE” OR “FALSE”) only.

How to Use the NOT Function in Excel?

NOT Function in Excel is very simple and easy to use. Let us now see how to use the NOT function in excel with the help of some examples.

Example #1 – Excel NOT Function

Here a logical test is performed on the given set of values (Student score) by using the NOT function. Here, we will check which value is greater than or equal to 50.

In the table, we have 2 columns, the first column contains student score & the second column is the logical test column, where the NOT function is performed.

Result: It will return the reverse value if the value is greater than or equal to 50, then it will return FALSE and if the lesser than or equal to 50, it will return TRUE as output.

The result will be as given below:

Example #2 – Using NOT Function with ISBLANK

the logical test is performed on the H5 & H6 Cells by using the NOT Function along with ISBLANK function; here will check if cells H5 & H6 is blank OR not using NOT function along with ISBLANK in excel

OUTPUT will be TRUE.

Example #3 – NOT Function along with “IF” and “OR” Function

Here the color check is performed for the cars in the below-mentioned table by using NOT Function along with “if” and “or” function

Here we have to sort out color “WHITE” or “RED” from the given set of data

=IF(NOT(OR(H11=”RED”,H11=”WHITE”)),”x”,””) formula is used

This logical condition is applied on a Color column containing any car with color “RED” or “WHITE”,

if the condition is true, then it will return blank as output,

 

if not true, then it will return x as output

Example #4 – VALUE! Error

It Occurs when the supplied argument is not a logical or numeric value.

Suppose, if we give a range in the logical argument

Selected the range C22:D22 in the logical argument, i.e. =NOT (C22:D22)

a function returns a #VALUE error because the NOT function does not allow any range and can take only a logical test or argument or one condition.

Example #5 – NOT Function for an empty cell or blank or “0”

An empty cell or blank or “0” are treated as false, therefore “NOT” function returns TRUE

Here in the cell “I23”, the stored value is “0” suppose if I apply the “NOT” function with logical argument or value as “0” or “I23”, Output will be TRUE.

Example #6 – NOT Function for Decimals

When the value is decimal in a cell

Suppose if we take the argument as decimals, i.e. suppose if I apply the “NOT” function with logical argument or value as “225.25” or “c27”, Output will be FALSE.

Example #7 – NOT Function for Negative Number

When the value is a negative number in a cell

Suppose if we take the argument as a negative number, i.e. suppose if I apply the “NOT” function with logical argument or value as “-4” or “H27”, Output will be FALSE.

Example #8 – When the value or Reference is Boolean Input in NOT Function

When the value or reference is Boolean input (“TRUE” OR “FALSE”) in a cell.

Here in the cell “C31”, the stored value is “TRUE” suppose if I apply the “NOT” function with logical argument or value as “C31” or “TRUE”, Output will be FALSE. It will be vice versa if the logical argument is “FALSE”, i.e. the NOT function returns the “TRUE” value as output.
