Logical Functions In Excel (Explained)

by

Logical functions are a powerful tool in Excel to simplify complex decision-making processes. They can be used to compare values, text, or data and produce a result of either TRUE or FALSE.

The most common logical functions are IF, AND and OR. Let’s take a look at the specifics of each and how they can be used.

IF Function

Excel’s IF function allows you to logically compare a value and what you expect. The basic syntax of the IF function is as follows:

IF(condition, value_if_true, value_if_false)

  1. In the cell where you want to use the IF function, enter the =IF() formula.
  2. Inside the parenthesis, enter the condition that you want to test. For example, if you want to determine if a student has passed a class with a score of 40 or higher, you would enter the condition =C2>=40. (C2 is the cell that contains the number a student got in a specific subject)
  3. Next, enter the value you want to return when the value is true or false. We will write this formula like this =IF(C2>=40, “Pass”, ”Fail”)
  4. Press Enter to complete the function. The cell will now display “Pass” if the student’s score in cell C2 is 40 or higher and “Fail” if the student’s score in cell C2 is below 40.
  5. Drag the formula down to apply the function to multiple students.

AND Function

Excel’s AND function is a logical function that allows you to test multiple conditions simultaneously. The basic syntax of the AND function is as follows:

AND(condition1, condition2, …)

Step by Step Instructions:

  1. In the cell where you want to use the AND function, enter the =AND() formula.
  2. Inside the parenthesis, enter the conditions that you want to test. For example, if you want to determine if all students have scored greater than or equal to 40 in each subject, you would enter the conditions =AND(C2>=40, D2>=40, E2>=40). Press Enter to complete the function.
  3. The cell will now display “TRUE” if all the conditions are true and “FALSE” if any of the conditions are false.
  4. Drag the formula down to apply the function to multiple students.

OR Function

The OR function returns “TRUE” if any of the conditions are true and “FALSE” if all the conditions are false. The basic syntax of the OR function is as follows:

OR(condition1, condition2, …)

Step by Step Instructions for OR function:

  1. Open a new Excel spreadsheet and enter test data.
  2. In the cell where you want to use the OR function, enter the =OR() formula.
  3. Inside the parenthesis, enter the conditions that you want to test. For example, if you want to determine if a student passed by either scoring a total mark of 120 or passing a math test, you would enter the conditions =OR(C2>=40, F2>120). Press enter to complete the function.
  4. The cell will now display “TRUE” if any of the conditions are true and “FALSE” if all of the conditions are false.
  5. Drag the formula down to apply the function to multiple students.

NOT Function

The NOT function inverts the value of a logical or Boolean expression. The basic syntax of the NOT function is as follows:

NOT(logical)

Step by Step Instructions for NOT function:

  1. In the cell where you want to use the NOT function, enter the =NOT() formula.
  2. Inside the parenthesis, enter the logical expression that you want to invert. For example, if you want to determine if a student’s total mark is not less than 120, you can write it in this way = NOT(F2>120), where F2 contains the total numbers.
  3. Press enter to complete the function. The cell will now display “TRUE” if the logical expression is false and “FALSE” if the logical expression is true.
  4. Drag the formula down to apply the function to multiple students.

Conclusion

Using the IF, AND, OR, and NOT functions in Excel can help you quickly analyze data in a spreadsheet. We hope this guide has given you an overview of how to use these functions in Excel.
