Testing more than one condition
If you need to test for more than one condition, then take one of several actions, depending on the result of the tests, one option is to nest multiple IF statements together in one formula. You’ll often hear this referred to as “nested IFs”. The idea of nesting comes from embedding or “nesting” one IF function inside another. In the example shown, we are using nested IF functions to assign grades based on a score. The logic for assigning a grade goes like this: To build up a nested IF formula that reflects this logic, we start by testing to see if the score is below 64. If TRUE, we return “F”. If FALSE, we move into the next IF function. This time, we test to see if the score is less than 73. If TRUE, we return “D”. If FALSE, we move into yet another IF function. And so on. Eventually, the formula we have in cell D5 looks like this: You can see that it’s important in this case to move in one direction, either low to high, or high to low. This allows us to return a result whenever a test returns TRUE, because we know that the previous tests have returned FALSE.
Making nested IFs easier to read
By their nature, nested IF formulas can be hard to read. If this bothers you, you can add line breaks inside the formula to “line up” the tests and results. This video explains how to add line breaks to a nested if.
