The NOT function in Excel is a function that returns the inverse value of the reference value. This is a fairly common function, so almost everyone knows how to use it. But if you forget or don’t know how to use it, let’s follow the article below. FPT Shop will help you understand more about the NOT function and how to use it.

Concept and application of the NOT function in Excel

The NOT function is one of the basic logic functions in Excel, which returns the inverse value of the referenced function easily. The function helps you take the inverse value of the value you are using. In addition, it also helps you operate more professionally when using Excel. When combining the NOT function with many other functions, it can support your work well.

How to use the NOT function in Excel

The NOT function is widely used in Excel problems, so you need to understand the syntax and usage of this function. Below is the syntax and usage of the NOT function:

NOT function syntax

The syntax of the NOT function is: =NOT(value), where value is the value that needs to be verified. When using the NOT function, you need to pay attention to some issues: the NOT function is often used most in combination with the IF function if the statement contains a condition. The NOT function will return the TRUE value if it is a cell containing the FALSE value and vice versa will return FALSE if it is a cell containing the TRUE value. If a number value is given to the function like NOT(10), the function will return the FALSE value.

How to use

As mentioned above, the NOT function is used to get the inverse value of the value being used. To understand better, we illustrate the case: use the NOT function to find the inverse value. You need to follow two steps as follows to solve the problem:

  • Step 1: In the Excel worksheet, you enter the function =NOT(TRUE) in any reference cell to check.
  • Step 2: Press Enter to display the result and do the same for the data in the table, you will have the result of the problem.

Combining the NOT function with other logic functions in Excel

The NOT function is used in combination with many other functions to flexibly apply the advantages of each function to solve the problem. The NOT function is often combined with 3 functions: IF, AND, and OR.

Combined with the IF function

Let’s consider the following example of using the IF and NOT functions to classify the products that meet the standards in the table below. To perform the requirement, you need to follow the steps below:

  • Step 1: In the data of the Excel worksheet, you need to enter the function formula: =IF(NOT(B4<500),"meets","does not meet") to fill in the result cell to check.

Using the IF function in this way, change the result name from True/False to the Result Meets/Does not meet. IF and NOT are function commands. B4<500: is the data of cell A3 with the given condition must be less than 500. And "meets", "does not meet": the condition to display the result.

  • Step 2: Press Enter to display the result and use the mouse pointer to drag to display the remaining results in the problem.

Combined with the AND function

Step 1: In the worksheet, you enter the function =IF(AND(NOT(B4>1),NOT(B4<=10)),b4,"the value="" is="" not="" in="" the="" range")="" in="" any="" reference="" cell="" to="" check.="" IF,="" AND,="" and="" NOT="" here="" are="" function="" commands.="" The="" calculation="" condition="" in="" the="" function="" is="" (NOT(B4>1),NOT(B4<>. And “value is not in the range”: is the result displayed if the calculation condition is not met.

Step 2: Press Enter to display the result and use the mouse pointer to drag down to display the remaining results of the problem.

Combined with the OR function

Consider the example of assessing the math and literature scores of students. If any of the 2 scores below 5, the student will fail. We need to perform with two steps:

  • Step 1: Enter the function =IF(OR(NOT(B4>5),NOT(C4>5)),”Fail”,”Pass”) in any cell on the worksheet to check. IF, OR, and NOT here are function commands. (NOT(B4>5),NOT(C4>5)): understood as a calculation condition in the function. And “Fail”, “Pass”: the condition to display the result.

  • Step 2: Press Enter to display the result, use the mouse pointer to drag to display the remaining results of the problem.

Conclusion

In general, through the problem we have understood more about the NOT function as well as how to combine the NOT function with other functions in Excel. Having a strong grasp of this knowledge, you will perform Excel more proficiently, thereby improving your office computing skills, helping you solve exercises and work quickly and efficiently.

Frequently asked questions

The ‘NOT’ function in Excel is a logical function that reverses the outcome of a condition. It returns ‘TRUE’ if the specified condition evaluates to ‘FALSE’, and vice versa. For example, =NOT(A1=B1) will return TRUE if the value in cell A1 is not equal to the value in cell B1.

You can use the ‘NOT’ function in conjunction with other logical functions like ‘AND’, ‘OR’, and ‘IF’ to create more complex conditions and formulas. For instance, you could use =NOT(AND(A1=1, B1=2)) to return TRUE if either cell A1 does not equal 1 or cell B1 does not equal 2.

The ‘NOT’ function is useful for filtering data, validating input, and creating custom error messages. For example, you can use it to highlight cells that do not meet certain criteria or to display a message if a user enters invalid data. It’s also commonly used in financial modeling and data analysis to identify outliers or exceptions.

You can combine the ‘NOT’ function with the ‘FILTER’ function to filter data based on specific criteria. For instance, =FILTER(A:A, NOT(A:A>=100)) will return all values in column A that are less than 100.

It’s important to remember that the ‘NOT’ function only returns ‘TRUE’ or ‘FALSE’. It also evaluates each argument separately, so be careful when using it with functions that expect a range of cells as an argument. Additionally, nested ‘NOT’ functions can be confusing, so try to keep your formulas as simple as possible.
