VBA-Excel: User Define Functions

Microsoft Excel has lot of built in formulas like Sin(), Avg() and many more, which we discuss in detail in future articles, but apart from that you can write your own functions which will act as any other built-in formula in excel , Which is one of the powerful  feature of Excel.

Like other formulas, you can apply your function in each cell or range of cells.

Syntax:

Public Function functionName (Arg As dataType,……….) As dataType

or

Private Function functionName (Arg As dataType,……….) As dataType

Arg As dataType -> data type of argument

The second data type is the return type of function.

Public : The function is applicable to the whole project.
