I have the following problem. I need to log changes in a spreadsheet. My range goes from A1:M300000.
So far I have managed to log the address of the changed cell, the user, the old value, and the new value.
Now I would like to insert the following functions and need help. It's the first time I come into contact with VBA:
I also want my log file to show the value of a cell in another column. So I know which object it is. Example change cell B26 and now also A26 should be displayed in the log file.
Furthermore, I also want to log when new cells are inserted or existing records are deleted.
Here is my VBA code:
Option Explicit
Dim mvntWert As Variant
Private Sub Worksheet_Change(ByVal Target As Range)
Dim wks As Worksheet
Dim lngLast As Long
Set wks = Worksheets("Protokoll")
lngLast = wks.Range("A65536").End(xlUp).Row + 1
If Target.Count > 1 Then Exit Sub
If Intersect(Range("A1:M65536"), Target) Is Nothing Then Exit Sub
With wks
.Range("A" & lngLast).Value = Target.Address(0, 0)
.Range("B" & lngLast).Value = mvntWert
.Range("C" & lngLast).Value = Target.Value
.Range("D" & lngLast).Value = VBA.Environ("Username")
.Range("E" & lngLast).Value = Now
End With
End Sub
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Target.Count > 1 Then Exit Sub
If Intersect(Range("A1:M65536"), Target) Is Nothing Then Exit Sub
mvntWert = Target.Value
End Sub
I hope someone can help me. Thank you very much in advance.

Please, try the next code, I prepared yesterday for somebody else asking for a similar issue. It needs only one event and should do what you require here:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim RangeValues As Variant, r As Long, boolOne As Boolean, TgValue 'the array to keep Target values (before UnDo)
Dim sh As Worksheet: Set sh = Worksheets("Protokoll")
Dim UN As String: UN = Application.userName
'sh.Unprotect "" 'it should be good to protect the sheet
If sh.Range("A1") = "" Then sh.Range("A1").Resize(1, 6) = _
Array("Time", "User Name", "Changed cell", "From", "To", "Sheet Name")
Application.ScreenUpdating = False 'to optimize the code (make it faster)
Application.Calculation = xlCalculationManual
If Target.cells.count > 1 Then
TgValue = extractData(Target)
Else
TgValue = Array(Array(Target.value, Target.Address(0, 0))) 'put the target range in an array (or as a string for a single cell)
boolOne = True
End If
Application.EnableEvents = False 'avoiding to trigger the change event after UnDo
Application.Undo
RangeValues = extractData(Target) 'define the RangeValue
putDataBack TgValue, ActiveSheet 'put back the changed data
If boolOne Then Target.Offset(1).Select
Application.EnableEvents = True
Dim columnHeader As String, rowHeader As String
For r = 0 To UBound(RangeValues)
If RangeValues(r)(0) <> TgValue(r)(0) Then
sh.cells(rows.count, 1).End(xlUp).Offset(1, 0).Resize(1, 6).value = _
Array(Now, UN, RangeValues(r)(1), RangeValues(r)(0), TgValue(r)(0), Target.Parent.Name)
End If
Next r
'sh.Protect ""
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic
End Sub
Sub putDataBack(arr, sh As Worksheet)
Dim i As Long, arrInt, El
For Each El In arr
sh.Range(El(1)).value = El(0)
Next
End Sub
Function extractData(rng As Range) As Variant
Dim a As Range, arr, count As Long, i As Long
ReDim arr(rng.cells.count - 1)
For Each a In rng.Areas 'creating a jagged array containing the values and the cells address
For i = 1 To a.cells.count
arr(count) = Array(a.cells(i).value, a.cells(i).Address(0, 0)): count = count + 1
Next
Next
extractData = arr
End Function
