looping worksheets

[Dummy Excel]

Hi All,
I have spreadsheet A and im trying to create a macro where it opens up spreadsheet B copies the worksheets out of spreadsheet B (could be one could be more) into spreadsheet A. Then go back into the spreadsheet B unmerge & copy then go into spreadsheet A and paste the data into my lookup table. Then goes back to spreadsheet B and does the same thing for the other worksheets (if any).Once thats done, close spreadsheet B, then loop and do it again for all the files within the folder.
The section of my code for the loop is below, although I cant get the looping correct for each worksheet in spreadsheet B - Any help will greatly be appreciated.

ChDir strPath
strExtension = Dir(strPath & "*.xlsx")

        Do While strExtension <> ""
            Set wbOpen = Workbooks.Open(strPath & strExtension)
         
            With wbOpen
                StatusReport = ActiveWorkbook.Name
                Windows(StatusReport).Activate
            For Each ws In Worksheets
                    ws.Copy after:=Workbooks("Flightplan.xlsx").Sheets(2)
                Windows(StatusReport).Activate
                ws.Range("C5").Select
                ws.Range("C5").UnMerge
                ws.Range("C5").Copy
                Windows(Flightplan).Activate
                Sheets("Lookup Table").Activate
    
                For i = 1 To ws.Range("A" & Rows.Count).End(xlUp).Row
                If Range("A" & i + 1).Value = "" Then
                Range("A" & i + 1).PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
                    :=False, Transpose:=False
                Else
                ws.Range("A1").End(xlDown).Offset(1, 0).Select
                ws.Range("A" & i + 1).PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
                    :=False, Transpose:=False
                End If
                End If
                
                Next i
    
            Next
                Windows(StatusReport).Activate
    
                Application.DisplayAlerts = False
                ActiveWorkbook.Close
                Application.DisplayAlerts = True
    
            End With
            
            strExtension = Dir
        Loop

PS the reason for going back & forth is because in spreadsheet A I need the merged cells, so rather than unmerge copy then go back and merge I thought it would be easier going back and forth!

no one?

bump?

Do I need to try and explain it differently?
All im trying to do is copy a worksheet from ss A to ss B, then go back to ss A and copy a few cells. If there are mutilple worksheets do it for all worksheets.
Ive got the loop for coping all the worksheets, although I cant get the coping working?
