Hi I have two problems. I need my spreadsheet to automatically make a backup copy of itself each day, with the file name to include the date. Is that even possible?

Also, when any cell in a row is changed, I would like a cell at the end of that row to show the now() date, time and the user. I have tried: but it changes the time of ALL the rows above, up to the one that has changed.

Public Function Lastmodified(c As Range)


Lastmodified = Now()


End Function

Thank you in advance for any help

Which Excel functions can ignore hidden rows?
The SUBTOTAL and AGGREGATE functions ignore hidden rows. AGGREGATE can also exclude error cells and more.
Code:

You cannot do that by formula - the formula updates when the sheet is calculated

Place code below in the SHEET module
- amend to what you want to happen
- currently monitor columns A to Y and places the value in Z
- cell in column Z is updated with every edit to any cell in the same row in columns A to Y

Code:
Private Sub Worksheet_Change(ByVal Target As Range)
    If Not Intersect(Target, Range("A:Y")) Is Nothing Then Range("Z" & Target.Row) = Now
End Sub

Try something like this
- it saves to the same folder as the workbook whenever the workbook is closed
- message box added to provide user with option if workbook is opened and closed several times in a day
- amend to suit your own requirements

Place code in ThisWorkbook module (it does NOT work in a standard module)
Code:
Private Sub Workbook_BeforeClose(Cancel As Boolean)
    Call BackupCopy
End Sub

Private Sub BackupCopy()
    If MsgBox("Create a backup?", vbYesNo) <> vbYes Then Exit Sub
    Dim Nm As String, Extn As String, fNm
    With ThisWorkbook
        fNm = .FullName
        Nm = Mid(fNm, 1, InStrRev(fNm, ".") - 1)
        Extn = Replace(fNm, Nm, "")
    End With
    Application.DisplayAlerts = False
    ThisWorkbook.SaveCopyAs Nm & " backup " & Format(Date, "YYMMDD") & Extn
    Application.DisplayAlerts = True
End Sub

This is brilliant. Thank you so much, it works perfectly. Ideally I would like the user name too but I can live without that.

Ideally I would like the user name too
Code:
Private Sub Worksheet_Change(ByVal Target As Range)
        If Not Intersect(Target, Range("A:Y")) Is Nothing Then Range("Z" & Target.Row).Resize(, 2) = Array(Now, Application.UserName)
End Sub

which places Excel user name in the cell
To use the Windows user name replace Application.UserName with Environ("UserName")
