Laurie knows how to view properties of an Excel workbook. What she would like to do, however, is to view similar properties relative to individual worksheets. For instance, she wonders if there is a way to view properties such as date created, date modified, author, or "last modified by" for individual worksheets.
Unfortunately, Excel doesn't keep track of such information for worksheets. The only workaround we've been able to figure out is to develop your own record of information about the worksheets in the workbook. An obvious way to do develop a Workbook_SheetChange event handler. The following is an example of one you could add to the ThisWorkbook object in the Visual Basic Editor:
Private Sub Workbook_SheetChange(ByVal ws As Object, ByVal Target As Range) Dim s As Worksheet Dim J As Integer Dim FoundIt As Boolean On Error Resume Next Set s = Worksheets("Stats") On Error GoTo 0 Application.EnableEvents = False If s Is Nothing Then ' Stats worksheet did not exist Set s = Worksheets.Add(After:=Worksheets(Worksheets.Count)) s.Name = "Stats" s.Range("A1") = "Worksheet" s.Range("B1") = "Creator" s.Range("C1") = "Last Modified" s.Range("D1") = "Modifed By" With s.Range("A1:D1") .Font.Bold = True .Borders(xlEdgeBottom).LineStyle = xlContinuous .Borders(xlEdgeBottom).Weight = xlThin End With s.Range("A2") = s.Name s.Range("B2") = s.CustomProperties.Creator s.Range("C2") = Format(Now, " mm/dd/yyyy hh:mm am/pm") s.Range("D2") = Application.UserName End If J = 2 FoundIt = False While (s.Cells(J, 1) <> "") If s.Cells(J, 1) = ws.Name Then FoundIt = True s.Cells(J, 3) = Format(Now, " mm/dd/yyyy hh:mm am/pm") s.Cells(J, 4) = Application.UserName End If J = J + 1 Wend If Not FoundIt Then ' Worksheet name not found s.Cells(J, 1) = ws.Name s.Cells(J, 2) = ws.CustomProperties.Creator s.Cells(J, 3) = Format(Now, " mm/dd/yyyy hh:mm am/pm") s.Cells(J, 4) = Application.UserName End If ws.Activate Application.EnableEvents = True End Sub
The event handler is triggered anytime you make a change in the workbook. It first checks to see if there is a worksheet named Stats. If not, then the worksheet is created, and some rudimentary information is added to it. The handler looks in the Stats worksheet to determine if the data there includes a row for the worksheet on which a change occurred. If not, then a row is added, but if so, the information in the row is updated.
The handler only tracks four pieces of information—the worksheet name, the creator, the date the last change was made, and the user name of who made the change. (The Creator property indicates a numeric value related to the program that created the worksheet. It isn't terribly helpful for humans, and I included it as an illustrative example of how information can be stored.)
Remember, this is only a workaround and you should consider carefully what type of information you want to track for your worksheets. You can then modify the code to reflect that desire.
