将文件夹中的文件 csv 导入单个工作表

Question

我使用下面的代码将多个 CSV 文件放入单个工作表中。

代码工作正常，但问题是，它不应该复制每个文件的标题，因为每个文件标题都是相同的。

代码应该复制第一个文件头而不是所有文件。

还有一件事，我不希望第一列复制所有工作表名称，我试图删除该文件，但代码不起作用。

我能得到任何帮助吗？ 谢谢

Sub CSV()
Dim xSht As Worksheet
Dim xWb As Workbook
Dim xStrPath As String
Dim xFileDialog As FileDialog
Dim xFile As String
On Error GoTo ErrHandler
Set xFileDialog = Application.FileDialog(msoFileDialogFolderPicker)
xFileDialog.AllowMultiSelect = False
xFileDialog.Title = "Select a folder [Kutools for Excel]"
If xFileDialog.Show = -1 Then
xStrPath = xFileDialog.SelectedItems(1)
End If
If xStrPath = "" Then Exit Sub
Set xSht = ThisWorkbook.ActiveSheet
Application.ScreenUpdating = False
xFile = Dir(xStrPath & "\" & "*.csv")
Do While xFile <> ""
Set xWb = Workbooks.Open(xStrPath & "\" & xFile)
Columns(1).Insert xlShiftToRight
Columns(1).SpecialCells(xlBlanks).Value = ActiveSheet.Name
ActiveSheet.UsedRange.Copy xSht.Range("A" & Rows.Count).End(xlUp).Offset(1)
xWb.Close False
xFile = Dir
Loop
Application.ScreenUpdating = True
Exit Sub
ErrHandler:
MsgBox "no files csv", , "Kutools for Excel"
End Sub

编辑：我做了两次尝试，第一次未经测试，并在我的手机上完成了：

Sub CSV()
    Dim xSht As Worksheet
    Dim xWb As Workbook
    Dim xStrPath As String
    Dim xFileDialog As FileDialog
    Dim xFile As String
    On Error GoTo ErrHandler
    Set xFileDialog = Application.FileDialog(msoFileDialogFolderPicker)
    xFileDialog.AllowMultiSelect = False
    xFileDialog.Title = "Select a folder [Kutools for Excel]"
    If xFileDialog.Show = -1 Then
        xStrPath = xFileDialog.SelectedItems(1)
    End If
    If xStrPath = "" Then Exit Sub
    Set xSht = ThisWorkbook.ActiveSheet
    Application.ScreenUpdating = False
    xFile = Dir(xStrPath & "\" & "*.csv")
    Dim counter as Long
    Do While xFile <> ""
        Set xWb = Workbooks.Open(xStrPath & "\" & xFile)
        Dim sourceRange as Range
        Set sourceRange = xWb.Worksheets(1).UsedRange
        If counter = 0 then
            sourceRange.Copy xSht.Range("A" & Rows.Count).End(xlUp).Offset(1)
        else
            sourceRange.Offset(1, 0).Resize(sourceRange.Rows.Count - 1, sourceRange.Columns.Count).Copy xSht.Range("A" & Rows.Count).End(xlUp).Offset(1)
            
        End If
        xWb.Close False
        xFile = Dir
        counter = counter + 1
    Loop
    Application.ScreenUpdating = True
    Exit Sub
    ErrHandler:
    MsgBox "no files csv", , "Kutools for Excel"
End Sub

在我的计算机上进行第二次尝试，我重构了处理第一个文件大小写的代码，跳过了剪贴板并使用了正确的过程和变量名称。
