Hi Aymanh
You need VBA to do that
You can do it with the change event of the worksheet
This example will place the date/time in the B column if you change
a cell in the range A1:A20.
Place the code in the Sheet module
Right click on a sheet tab and choose view code
Paste the code there
Alt-Q to go back to Excel
Private Sub Worksheet_Change(ByVal Target As Range)
If Not Application.Intersect(Range("a1:a20"), Target) Is Nothing Then
Target.Offset(0, 1).Value = Format(Now, "mm-dd-yy hh:mm:ss")
End If
End Sub
Manual you can do this
you can insert the time like this
CTRL : (colon)
the date like this
CTRL ; (semicolon)
CTRL : (colon) space bar CTRL ; (semicolon)
this will give you both in one cell
