What should be done before writing a nested IF function?

Before writing a nested IF function, it is essential to understand the logical conditions that will be tested. This understanding allows you to define clear and precise criteria for each branch of your nested IF statements. A well-structured approach starts with identifying the various scenarios and outcomes you need to evaluate. It ensures that each condition is appropriately handled, leading to accurate results.

Having a solid grasp of the logic behind the nested IF function helps you to avoid errors in your formulas, as it requires careful attention to how different conditions relate to one another. Once you know what conditions you are checking for and what results should be returned for each scenario, you can effectively organize your IF statements in a way that is both functional and efficient.
