vba实现excel多表合并

Excel多表合并之vba实现

需求

保留列名，复制每一个excel里的数据，合并到一个excel

操作步骤

1. 将要合并的文件放在同一文件夹下，复制过来就好（ps：最好不要直接操作原数据文件，避免操作失败，数据丢失）
2. 在这个目录下创建一个“合并.xlsx”
3. 双击打开“合并.xlsx”
4. 同时按 ALT + F11
5. 出现下图，按图中文字操作即可完成合并

1. 完成

附录代码

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
    flag = 

    Application.ScreenUpdating = False
    MyPath = ActiveWorkbook.Path
    MyName = Dir(MyPath & "\" & "*.xls")
    AWbName = ActiveWorkbook.Name
    Num = 

    Do While MyName <> ""

合并多个excel每个excel有多个sheet，每个sheet单独合并，代码如下

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
    flag = 0

    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

                For G = 1 To Wb.Sheets.Count

                    If flag = 0 Then
                    Sheets.Add after:=Sheets(Sheets.Count)

                        With ActiveSheet
                               .Name = Wb.Sheets(G).Name
                           Wb.Sheets(G).UsedRange.Copy .Cells(.Range("A65536").End(xlUp).Row, 1)
                           .UsedRange.Rows.AutoFit

                          With Workbooks(1).Worksheets(G + 3)
                          ' MsgBox .Name & "--" & Wb.Sheets(G).Name
                           If G = 2 Then
                            Wb.Sheets(G).Range("a2", Wb.Sheets(G).Cells.SpecialCells(xlCellTypeLastCell)).Copy .Cells(.Range("A65536").End(xlUp).Row + 2, 1)
                           Else

                Next
                'flag 为0时候为第一个打开的excel，此时产生列，sheet名
                 flag = 1
                WbN = WbN & Chr(13) & Wb.Name
                Wb.Close False
