我建的宏:

 

Sub 合并文件的VBA()

Dim MyPath, MyName, AWbName

Dim Wb As Workbook, WbN As String

Dim G As Long

Dim Num As Long

Dim BOX As String

Application.ScreenUpdating = False

MyPath = ActiveWorkbook.Path

MyName = Dir(MyPath & "\" & "*.csv")

AWbName = ActiveWorkbook.Name

Num = 0

Do While MyName <> ""

If (MyName <> AWbName) And InStr(MyName, "PMT") = 0 Then

Set Wb = Workbooks.Open(MyPath & "\" & MyName)

Num = Num + 1

With Workbooks(1).ActiveSheet

.Cells(.Range("B1", "B100").End(xlUp).Row, 1) = Left(MyName, Len(MyName) - 4)

For irow = 1 To 100

.Cells(irow, 1) = Wb.Sheets(1).Cells(irow, 1)

Next

For G = 1 To Sheets.Count

For irow = 1 To 100

.Cells(irow, Num + 1) = Wb.Sheets(G).Cells(irow, 2)

Next

Next

WbN = WbN & Chr(13) & Wb.Name

Wb.Close False

End With

End If

MyName = Dir

Loop

Range("B1").Select

Application.ScreenUpdating = True

MsgBox "共合并了" & Num & "个工作薄下的全部工作表。如下：" & Chr(13) & WbN, vbInformation, "提示"

End Sub
