Let’s see some more example of the switch statement, such as

For example, you want to create a custom function (UDF) using the switch statement.

It can be used just like any regular worksheet function, and it will return the grade of the students.

The code for creating the custom formula as follows:

Now, you can use the function GetGrade in the worksheet as shown in the below screenshot, such as:
