Merge Workbooks to Master Workbook

[donb1337]

Hi guys,

at the moment I'm trying to consolidate four Workbooks to a Master Workbook.

The four Workbooks I want to merge have the same table structure but except the "Project Number" they have almost different data in their columns.

What I want to do is creating a Master Workbook in which all the Projects are listed once with the information of all four Lists.


I think I know what to do but I don't know how to do it...


While consolidating the data should be checked whether it is already in the Master Workbook or not:
If yes the Macro should copy the adding data in the existing Project row and there in the correct column.
If not the Macro should create a new row for the Project. <- So there should be something like "+1".

I think the problem could be to define in which column what information should be copied.
At the moment I already set header in the Master Workbook. Does that makes sense or is there a smarter way to simplify it?
The point is that I should be able to control which data will be copied in which column.

To make it easier for you to understand what I'm talking about I created an Example file in which the four Workbooks plus the Master Workbook are and attached it.


Any kind of help is really appreciated! Thanks in advance!

don, I see only 1 workbook attached. Do you mean that you've got 5 sheets in all in that one workbook?

[Excel Fox]

OK, apparently, you've clarified that in the attachment. Your sheets actually represent the individual workbooks.

[donb1337]

Yes exactly. Do you have any idea or advice for me Excel Fox?

Cheers!

This is the code I'm working with. There are no errors but something goes wrong with the copying and I have no idea what.


Sub MergeWorkbooks ()
Dim choice As Integer, rng As Range
Dim lrw As Long
Dim lcol As Integer

' Case 1 = last row
' Case 2 = last column
' Case 3 = last cell

Select Case choice

Case 1:
On Error Resume Next
RDB_Last = rng.Find(What:="*", _
after:=rng.Cells(1), _
Lookat:=xlPart, _
LookIn:=xlFormulas, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False).Row
On Error GoTo 0

Case 2:
On Error Resume Next
RDB_Last = rng.Find(What:="*", _
after:=rng.Cells(1), _
Lookat:=xlPart, _
LookIn:=xlFormulas, _

SearchDirection:=xlPrevious, _
MatchCase:=False).Column
On Error GoTo 0

Case 3:
On Error Resume Next
lrw = rng.Find(What:="*", _
after:=rng.Cells(1), _
Lookat:=xlPart, _

On Error Resume Next

after:=rng.Cells(1), _
Lookat:=xlPart, _
LookIn:=xlFormulas, _
SearchOrder:=xlByColumns, _
SearchDirection:=xlPrevious, _
MatchCase:=False).Column
On Error GoTo 0

On Error Resume Next
RDB_Last = rng.Parent.Cells(lrw, lcol).Address(False, False)
If Err.Number > 0 Then
RDB_Last = rng.Cells(1).Address(False, False)
Err.Clear
End If
On Error GoTo 0

End Select

Don, took a while, but here's the code you need

EndSub:

End Sub


I've also attached the workbook with the code. Just press CTRL+SHIFT+R (I've assigned that shortcut to the macro). It will then ask for the 4 workbooks to be selected. Select all 4, and click OK.

Let me know if you face any problem

Thank you so much for taking the time to reply, I really appreciate your help
Excel Fox. I will try the code asap and inform you how it went.
