If you wanted to time, date, and user stamp every change made in the first
300 rows you can do something like this. The stamps for A1:Z300 would
appear in AA1:AZ300 off creen to the right or you could hide that area so
only you would know it's there. Just change the offset if you want it
somewhere else. If the currently active Offset and Application.Username
lines don't produce the name you expect, comment them out and activate the
offset and Environ("username") lines by changing the apostrophes at the
beginning of those two lines. Paste this into the worksheet by right mouse
clicking the worksheet tab and selecting View Code.
Private Sub Worksheet_Change(ByVal Target As Range)
On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Me.Range("A1:Z300")) Is Nothing Then

.Offset(0, 26).Value = Format(Now, "dd mmm yyyy hh:mm ") _
& Application.UserName
'.Offset(0, 26).Value = Format(Now, "dd mmm yyyy hh:mm ") _

End With
End If
ws_exit:
