Invoking Excel Functions in VBA Instructions

If a VBA function that’s equivalent to one you use in Excel isn’t available, you can use Excel’s worksheet functions directly in your VBA code. Just precede the function with a reference to the WorksheetFunction object. For example, VBA doesn’t have a function to convert radians to degrees, but Excel has a worksheet function for this procedure, so you can use a VBA instruction such as the following:

Deg = Application.WorksheetFunction.Degrees(3.14)
