可以通过更改excel代码来合并多个文件。
详细步骤：
1、新建一个文件夹。
2、将要合并的表格放到里面。
3、新建一个表格。
4、用excel打开。
5、右击Sheet1。
6、选择查看代码。
7、将下列代码复制到文本框中：
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
.Cells(.Range("B65536").End(xlUp).Row + 2, 1) = Left(MyName, Len(MyName) - 4)
For G = 1 To Sheets.Count
Wb.Sheets(G).UsedRange.Copy .Cells(.Range("B65536").End(xlUp).Row + 1, 1)
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
8、点击运行，即可成功合并。

操作软件：Excel2016
1、将需合并的Excel文件放在同一个文件夹中。
2、打开新建的Excel文件，按 Alt + F11 键，打开宏，选择视图→代码窗口。
3、将下面的代码拷贝粘贴到代码窗口中：
Sub sheets2one()
'定义对话框变量
Dim cc As FileDialog
Set cc = Application.FileDialog(msoFileDialogFilePicker)
Dim newwork As Workbook
Set newwork = Workbooks.Add
With cc
If .Show = -1 Then
Dim vrtSelectedItem As Variant
Dim i As Integer
i = 1
For Each vrtSelectedItem In .SelectedItems
Dim tempwb As Workbook
Set tempwb = Workbooks.Open(vrtSelectedItem)
tempwb.Worksheets(1).Copy Before:=newwork.Worksheets(i)
newwork.Worksheets(i).Name = VBA.Replace(tempwb.Name, ".xls", "")
tempwb.Close SaveChanges:=False
i = i + 1
Next vrtSelectedItem
End If
End With
Set cc = Nothing
End Sub
4、点击菜单“运行”—“运行子过程/用户窗体”。
5、在弹出选择对话框中，选择要批量合并的Excel文件，点击“确定”即可合并为一个Excel工作簿。
6、点击“确定”后，运行合并即可。
合并方法如下：
1.需要把多个excel表都放在同一个文件夹里面，并在这个文件夹里面新建一个excel。如图所示：
2.用microsoft excel打开新建的excel表，并右键单击sheet1，找到“查看代码”，单击进去。进去之后就看到了宏计算界面。如图所示：
3.然后把下面这些宏计算的代码复制进去，然后找到工具栏上面的“运行”下的“运行子过程/用户窗体”，代码如下，如图所示：
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
.Cells(.Range("B65536").End(xlUp).Row + 2, 1) = Left(MyName, Len(MyName) - 4)
For G = 1 To Sheets.Count
Wb.Sheets(G).UsedRange.Copy .Cells(.Range("B65536").End(xlUp).Row + 1, 1)
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
4.运行之后，等待10秒针左右，等运行完毕，就是合并完成之后，会有提示，点确定就可以了。查看合并后的数据，有5000多行，就是同一个文件夹里面17个excel表数据合并后的结果。效果如图所示。
