      Read more post "How to use if function in Excel with multiple criteria [Part 1]" at here

      If you need to create more elaborate logical tests for your data, you can include additional IF statements in the value_if_true and value_if_false arguments of your Excel IF formulas. These multiple IF functions are called "nested IF functions" and they may prove particularly useful if you want your formula to return 3 or more different results.

     Here's an easy-to-understand example. Suppose you want not simply to qualify the students' results as Pass/Fail, but rather define the total score as "Good", "Satisfactory" and "Poor". For example:

        - Good: 60 or more (>=60)
        - Satisfactory: between 40 and 60 (>40 and <60)
        - Poor: 40 or less (<=40)

     To begin with, you can add an additional column (E) with the following formula that sums numbers in columns C and D: =C2+D2



       And now, let's write a nested IF function based on the above conditions. It's considered a good practice to start with the most important condition and make your functions as simple as possible. Our Excel nested IF formula is as follows:

=IF(E2>=60, "Good", IF(E2>40, "Satisfactory", "Poor "))

       As you see, just one nested IF function is sufficient in this case. Naturally, you can nest more IF functions if you want to. For example:

=IF(E2>=70, "Excellent", IF(E2>=60, "Good", IF(E2>40, "Satisfactory", "Poor ")))

      The above formula adds one more conditions - the total score of 70 points and more is qualified as "Excellent".


      I've heard some people say that multiple Excel IF functions are driving them crazy : ) Probably, it will help if you try to look at our nested IF formula in this way:


     What the formula actually tells Excel to do is to test the condition of the first IF function and return the value supplied in the  value_if_true argument if the condition is met. If the condition of the 1st IF function is not met, then test the 2nd IF, and so on.

=IF(check if E2>=70, if true - return "Excellent", or else 
   IF(check if E2>=60, if true - return "Good", or else
      IF(check if E2>40, if true - return "Satisfactory", if false
      - return " Poor ")))
