Show date of modification to one cell

[Pcesarrt26]

I have a set list of items and need to have a column that shows when the last time the cell next to it was modified. In the attached example column A will always be the same, column B will be modified periodically . I need column C to show the date of last modification of each items in column B. I know this can be achieved with VBA but have not really worked with VBA much. Column A will mostly likely have ~5k items in it

Maybe as shown in the attached file.

How did you do that?

Private Sub Worksheet_Change(ByVal Target As Range)

Dim rngBereich As Range

Set rngBereich = Range("B2:B2500")

If Not Application.Intersect(Target, rngBereich) Is Nothing Then

If Target.Value <> " " Then
Target.Offset(0, 1).Value = Date
Else

End If

End If

End Sub

This is done with the Worksheet_Change event and these lines of code.
