You don't provide too much information but you could build on this

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count 1 Or IsEmpty(Target) Then Exit Sub
If Target.Address = "$A$1" Then
If Target.Value = 123 Then
Target.Hyperlinks.Add Target, "http://www.google.co.uk/ig?hl=en"
End If
End If
End Sub
