新建一个工作表，命名后保存到和欲合并的几个文件同一个文件文件夹，摁 alt + f11,双击工程资源管理器里面的sheet1(sheet1),在右侧的代码区粘贴如下代码。运行。等候一会就OK了

Sub 合并当前目录下所有工作簿的全部工作表()
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 & "\" & "*.xls")
AWbName = ActiveWorkbook.Name
Num = 0
Do While MyName <> ""
If MyName <> AWbName Then
Set Wb = Workbooks.Open(MyPath & "\" & MyName)
Num = Num + 1
With Workbooks(1).ActiveSheet
If Num = 1 Then
For G = 1 To Sheets.Count
Wb.Sheets(G).UsedRange.Copy .Cells(.Range("A65536").End(xlUp).Row + 1, 1)
Next
Else
For G = 1 To Sheets.Count
Wb.Sheets(G).UsedRange.Offset(1, 0).Copy .Cells(.Range("A65536").End(xlUp).Row + 1, 1)
Next
End If
WbN = WbN & Chr(13) & Wb.Name
Wb.Close False
End With
End If
MyName = Dir
Loop
Range("A1").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
