CHOOSE
The CHOOSE() function is one of my favorite functions! It quickly allows me to “choose” from a defined list of values when aspecific events occur.
CHOOSE Formula
The CHOOSE function allows you to choose from a list of values using the index number as the list position
Example
CHOOSE(4, “Cactus”, 4, $B$3, “4th Quarter”) will return “4th Quarter” because the 4th value in the list is “4th Quarter”. The values provided to CHOOSE can include references, notice the cell reference $B$3 in the 3rd position of our list.
As with all functions in Excel, the versatility of this function is only limited to your imagination and use of nested functions.
The index number in the formula needs to be a whole number greater than or equal to 1. If the number is greater than the number of list items, the formula will return a #VALUE.
