Question

When I add a public function to a standard code module in Excel it shows up in the Insert Function wizard in the catch-all category “User Defined.”

Is there any way to:

1. Keep the function public (so it may be called from other modules) but hide it from the Excel function wizard?
2. Make the function appear in a built-in category (e.g., “Financial”, “Statistical”, “Logical”)?
3. Create my own category (e.g., “Nonsensical”) and have my function appear there?

I only need to be able to make one of the above cases work, but I’d be curious to know if each one is possible.

Note: I will gladly split this into three separate questions if the community feels that is more appropriate. I am thinking there may be a single answer with only slight variation among the three questions.

Answer 1

Application.MacroOptions is the command you are after

This example adds a user-defined macro called TestMacro to a custom category named My Custom Category.

Function TestMacro()
    MsgBox ActiveWorkbook.Name
End Function

Sub AddUDFToCustomCategory()
    Application.MacroOptions Macro:="TestMacro", Category:="My Custom Category"
End Sub
