Excel VBA-打開另一個工作簿並檢查工作表是否存在並合並

Question

我正在嘗試解決標題中所述的問題。 讓我解釋一下。 我正在嘗試通過選擇一個文件夾來合並多個工作表。 我設法通過使用以下代碼實現了這一點：

Option Explicit
Public strPath As String
Public Type SELECTINFO
hOwner As Long
pidlRoot As Long
pszDisplayName As String
lpszTitle As String
ulFlags As Long
lpfn As Long
lParam As Long
iImage As Long
End Type

Declare Function SHGetPathFromIDList Lib "shell32.dll" Alias "SHGetPathFromIDListA" (ByVal pidl As Long, ByVal pszPath As String) As Long
Declare Function SHBrowseForFolder Lib "shell32.dll" Alias "SHBrowseForFolderA" (lpBrowseInfo As SELECTINFO) As Long
Function SelectFolder(Optional Msg) As String
Dim sInfo As SELECTINFO
Dim path As String
Dim r As Long, x As Long, pos As Integer
sInfo.pidlRoot = 0&

If IsMissing(Msg) Then
    sInfo.lpszTitle = "Select your folder."
Else
    sInfo.lpszTitle = Msg
End If

sInfo.ulFlags = &H1

x = SHBrowseForFolder(sInfo)

path = Space$(512)
r = SHGetPathFromIDList(ByVal x, ByVal path)
If r Then
    pos = InStr(path, Chr$(0))
    SelectFolder = Left(path, pos - 1)
Else
    SelectFolder = ""
End If
End Function

"Merging Part"
Sub MergeExcels()
Dim path As String, ThisWB As String, lngFilecounter As Long
Dim wbDest As Workbook, shtDest As Worksheet, ws As Worksheet
Dim Filename As String, Wkb As Workbook
Dim CopyRng As Range, Dest As Range
Dim RowofCopySheet As Integer

RowofCopySheet = 1 

ThisWB = ActiveWorkbook.Name

path = SelectFolder("Select a folder containing Excel files you want to merge")

Application.EnableEvents = False
Application.ScreenUpdating = False

Set shtDest = ActiveWorkbook.Sheets(1)
Filename = Dir(path & "\*.xls", vbNormal)
If Len(Filename) = 0 Then Exit Sub
Do Until Filename = vbNullString
    If Not Filename = ThisWB Then
        Set Wkb = Workbooks.Open(Filename:=path & "\" & Filename)
        Set CopyRng = Wkb.Sheets(1).Range(Cells(RowofCopySheet, 1), Cells(ActiveSheet.UsedRange.Rows.Count, ActiveSheet.UsedRange.Columns.Count))
        Set Dest = shtDest.Range("A" & shtDest.UsedRange.SpecialCells(xlCellTypeLastCell).Row + 1)
        CopyRng.Copy Dest
        Wkb.Close False
    End If

    Filename = Dir()
Loop

Range("A1").Select

Application.EnableEvents = True
Application.ScreenUpdating = True

MsgBox "Files Merged!"
End Sub

我什至設法調整了上面的代碼以合並目標工作簿的第二張表。

但是，在我的新任務中，我必須檢查“ Data2”表的存在。 如果存在，我想將所有這些工作表合並到我的當前工作簿中。

謝謝。

嘗試這個：

'Merging Part
Sub MergeExcels()
Dim path As String, ThisWB As String, lngFilecounter As Long
Dim wbDest As Workbook, wbSource As Workbook, shtDest As Worksheet, shtSource As Worksheet
Dim Filename As String
Dim CopyRng As Range, Dest As Range
Dim RowofCopySheet As Integer

RowofCopySheet = 1

ThisWB = ThisWorkbook.Name 'ActiveWorkbook.Name

path = SelectFolder("Select a folder containing Excel files you want to merge")

Application.EnableEvents = False
Application.ScreenUpdating = False

Set shtDest = ThisWorkbook.Sheets(1)
Filename = Dir(path & "\*.xls", vbNormal)
If Len(Filename) = 0 Then Exit Sub
Do Until Filename = vbNullString
    If Not Filename = ThisWB Then
        Set wbSource = Workbooks.Open(Filename:=path & "\" & Filename)
        For Each shtSource In wbSource.Worksheets ' loop through all worksheets
           If shtSource.Name = "Data2" Then 'if ther's a worksheet named "Data2"
                'Set CopyRng = shtSource.Range(Cells(RowofCopySheet, 1), Cells(ActiveSheet.UsedRange.Rows.Count, ActiveSheet.UsedRange.Columns.Count))
                Set CopyRng = shtSource.UsedRange ' copy the used Range / Filled Range
                Set Dest = shtDest.Range("A" & shtDest.UsedRange.SpecialCells(xlCellTypeLastCell).Row + 1)
                CopyRng.Copy Dest
           End If
        Next
        wbSource.Close False ' close the sourceworkbook
    End If
    Filename = Dir()
Loop

shtDest.Range("A1").Select

Application.EnableEvents = True
Application.ScreenUpdating = True

MsgBox "Files Merged!"
End Sub
