Extract the last substring from a cell

Question

I have names in a column. I need to split just the last names from that column into another column.

The last name is delimited by a space from the right side.

Answer 1

The answer provided by @Jean provides a working but obscure solution (although it doesn't handle trailing spaces)

As an alternative consider a vba user defined function (UDF)

Function RightWord(r As Range) As Variant
    Dim s As String
    s = Trim(r.Value)
    RightWord = Mid(s, InStrRev(s, " ") + 1)
End Function

Use in sheet as
=RightWord(A2)
