A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Event code is not all that hard to do. For example, if you wanted the date in the cell to the right of any single cell that changes on a sheet when it is changed, copy this code, right-click the sheet tab, select "View Code" and paste the code into the window that appears.
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
Application.EnableEvents = False
With Target(1, 2)
'Choose any date/time format you like
.NumberFormat = "mm/dd/yyyy hh:mm AM/PM"
.Value = Now
End With
Application.EnableEvents = True
End Sub
