Creating User-defined Functions in Excel

Is it true that using user-defined functions from worksheet cells will not degrade worksheet performance?

1. True
2. False

Answer:

A benefit of using user-defined functions from worksheet cells is that worksheet performance does not degrade, even with the function used in hundreds of thousands of cells with complex cell dependencies.

When you create a user-defined function in a worksheet cell, it can be reused in other cells without impacting worksheet performance. This is because the function's result is calculated once and stored in memory, rather than recalculated every time it is used. This is especially beneficial when dealing with complex formulas and large datasets that require extensive calculations.

For example, if you have a complex formula that needs to be used in multiple cells, you can create a user-defined function to perform the calculation once and then refer to that function in other cells. This improves efficiency and reduces the computational load on the worksheet, resulting in faster performance.
