Excel 2002 UDF

  Asked By: Jada    Date: Mar 14    Category: MS Office    Views: 1866

I have a formula I want to turn into a user defined function. The formula is
=LEFT(A1,FIND(" ",A1)-1)

Where cell A1 contains a name like John Smith, the formula will return the
text string "John".

What I want to do is create a user defined function in VBA, so I can use a
formula that might look like:


Could any kind person out there show me what the VBA code would look like
for this function?

Try this:

Function FirstName(pData As String)
iPos1 = InStr(pData, " ")
If iPos1 = 0 Then
FirstName = pData
FirstName = Left(pData, iPos1 - 1)
End If
End Function

Two ways (out of numerous)

Option Explicit

Public Function Version1(ByVal Cell As Range) As String
Version1 = Left(Cell.Value, InStr(Cell.Value, " ") - 2)
End Function

Public Function Version2(ByVal Cell As Range) As String
Dim Parts
Parts = Split(Cell.Value, " ")
Version2 = Parts(0)
End Function

Both assume that there is a space in there somewhere. If not, then the first
returns #VALUE (as indeed does your formula). The second assumes that the
person only has a first name and returns that.

I prefer to use string functions like



For example

Private Function FirstName(CellData as String)
FirstName = Mid(CellData,1,Instr(1,CellData,Chr(32)))
End Function

But one question. What if the name is "Michael J. Fox" or etc?

Maybe it should start to search from the end?
