Is there a way to make UDF that gives a description like the native Excel functions have when user clicks the Fx button?

Question

If I type =vlookup( (or any other native Excel function) in the formula bar and then click the little Fx button to the left of the formula I get a Function Argu

Answer 1

Create function like I have created below: Function CompanyNames:

Function CompanyNames(CompanyCode As Integer, Data As Range) As String

CompanyNames = WorksheetFunction.VLookup(CompanyCode, Data, 2, False)


End Function

Run below code once and you get the argument description in Function

Sub DescribeFunction()

Dim FuncName As String
Dim FuncDesc As String
Dim Category As String
Dim ArgDesc(1 To 2) As String

FuncName = "CompanyNames"
FuncDesc = "Returns the Company Name"

ArgDesc(1) = "Provide the Company Code"
ArgDesc(2) = "Select Range to lookup"


Application.MacroOptions _
  Macro:=FuncName, _
  Description:=FuncDesc, _
  Category:=Category, _
  ArgumentDescriptions:=ArgDesc
End Sub
