The function to use in this scenario is called SWITCH. Suppose you know what the letter grades are but you need to discover the test score ranges. (SIDE NOTE: The IFS function supports 127 separate evaluations, compared to 64 evaluations when nesting older IF function.) LetвЂ™s Flip the Question Notice there is only a SINGLE set of parentheses instead of four, or 64 in the worst case scenario. The new IFS function is not doing anything more or less than the original nested IF, but it performs the task more elegantly due to the removal of the redundant IF functions. Below is the same formula but accomplished with an IFS function. The new IFS function strips out the need for creating a new IF statement for each new evaluation. Using our current example of number grades to letter grades, we can greatly reduce the length and repetition of the original nested IF by using a new function called IFS. The formula becomes increasingly difficult to keep track of parenthetical pairing.Д®XCEL 2016 and New Functions Save the DayД®xcel 2016 is equipped with two new functions called IFS and SWITCH that help mitigate all of the above problems associated with multi-level nested IF statements.

ItвЂ™s big!) the longer the formula becomes.

The opportunity to make a typo increases exponentially (or geometrically whatever.

The length of the formula is becoming excessive.

Each function asks a variation on the same question about the same source data.

This formula is only determining five (5) possible outcomes, yet it suffers from several problems. The below table shows the ranges that grades fall into.ДЄssuming we name the cell containing the final score вЂњ scoreвЂќ, the formula to calculate the letter grade would look as follows: LetвЂ™s take the following example of determining letter grades based on test scores. (SIDE NOTE: It is often suggested that if you are writing more than 4 or 5 levels in a nested IF, you should really think about using a different function to accomplish your task, such as VLOOKUP.) This provides the user with up to 65 possible actions to take. ExcelвЂ™s IF has a limit of 64 nested levels. The nested IF is simply an IF inside of an IF, which could then be inside another IF.

What does one do if several evaluations need to take place? Enter the Nested IF This IF (sometimes referred to as a вЂњ simple IFвЂќ) has the built-in limitation of only being able to perform a single evaluation. The catch is that any question posed must be answerable as either вЂњ trueвЂќ or вЂњ falseвЂќ.ДЄ simple example would be something like, вЂњ Are the contents of cell A1 greater than the contents of cell B1?вЂќ If the answer is вЂњ yesвЂќ, calculate a 10% bonus if not, then no bonus is offered. The IF function provides the user the ability to ask a question and perform action вЂњ AвЂќ for one answer and action вЂњ BвЂќ for another answer. Some of the first functions that a newly-titled вЂњpower userвЂќ learn are IF and VLOOKUP.
