I have an Excel macro which is designed to create a new Excel tab ("Tracker") where changes made to any worksheet within the workbook are recorded, detailing "Cell Changed", "Old Value", "New Value", "Old Formula", "New Formula", "Time of Change", "Date of Change", and "User".

The macro currently will not detail the "Old Value" of the change where the target of the change are multiple cells, and instead shows as "Multiple Cells Selected" in the Tracker tab.

From what I can deduce, I need the declared variable "vOldValue" to equal a string created from the values from the selection, however I don't know how to achieve this.

Please see macro code below:

VBA Code:
Option Explicit
Dim sOldAddress As String
Dim vOldValue As Variant
Dim sOldFormula As String
 
Private Sub Workbook_TrackChange(Cancel As Boolean)
     
     
    Dim sh As Worksheet
    For Each sh In ActiveWorkbook.Worksheets
        sh.PageSetup.LeftFooter = "&06" & ActiveWorkbook.FullName & vbLf & "&A"
    Next sh
End Sub
 
Private Sub Workbook_SheetChange(ByVal sh As Object, ByVal Target As Range)

Any assistance would be greatly appreciated.

Thank you.
 
After a bit of tinkering (I must say I am really not sure here), I managed to get the "reason" being recorded for every change tracked by your script.
Here is what the macro does:
-tracks changes (including deletion as does yours)
-prevents multiple cell selection
-prevents execution of keystroke Ctrl+Z and Ctrl+Y which are the only flaw I found so far on the change tracking macro
-requests user for a reason for every change recorded and reports it in the Tracker page
VBA Code:

How to find 2nd largest value in a column?
MAX finds the largest value. =LARGE(A:A,2) will find the second largest. =SMALL(A:A,3) will find the third smallest
After some macro cleaning and re-testing on a machine other than mine, here is my version of your macro, including
-prevention of multiple cell selection
-prevention of combination Ctrl+Z and Ctrl+Y
-request to user for a reason for every change, record of reason in tracker

Very nice work!
Actually I was searching for same idea and got your code above. I tested it, it was working fine.

I need to request one thing:
Is it possible to link to that particular modified cell?

code like : Range(sOldAddress).Hyperlinks.Add (Mid(Range(sOldAddress), 28, 4))

Hello Samahiji.
Thank you for the kind words. Yet as mentioned above this is not only my work. I just tried to group it in one file.
I gave a try at turning cell addresses into hyperlinks
The following piece of code were added
VBA Code:
Dim rActiveCell As Range

VBA Code:
 Set rActiveCell = ActiveCell
and
VBA Code:
       .Hyperlinks.Add Anchor:=rActiveCell.Offset(1), Address:=sOldAddress, _
        ScreenTip:="Click to go to " & sOldAddress, _
        TextToDisplay:="Link to " & sOldAddress

So with the code below I could get the hyperlink displayed in "Tracker", but somehow it won't open the actual worksheet and activate the cell in question. I did not even test if a second or a a third change will also display the hyperlink properly in "Tracker". I hope this helps:
VBA Code:

Dim rActiveCell As Range

Hello Nicolaw81
Thanks for your quick response.

I've tested the code above, but it creates a new sheet for hyperlink instead of modifying sheets "Tracker"

The reason why it won't open the actual worksheet is that the subaddress should be in the following format: 'Sheet name'!cell name exactly with single qoute >> ', while the target cell contains file name as well.

OK I don't know how much this helps anyone, but I figured a way to include a request for a username & password at opening of workbook.
The following tabs must be created by default in the workbook:
  • 'Users',
  • 'Passwords',
  • 'Tracker'.
Usernames are stored in column A of "Users" tab, while PW are stored in corresponding cell in column A of "Passwords" tab.
In the future, I'd recommend admin of this file to PW protect these two sheets or hiding them.

I still have a defect to correct (any help welcome) in Tracker when a formula is changed I get a "#VALUE!" warning in the "Old Value" and "New Value" columns of the "Tracker" worksheet 🧐

also, I would like to have each change validated with a PW request prompt, but I am still not sure how to make this happen.
