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
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)
在这个目录下创建一个“合并.xlsx”
双击打开“合并.xlsx”
同时按 ALT + F11
出现下图，按图中文字操作即可完成合并
完成

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
.UsedRange.Columns.AutoFit
End With
Else
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
Wb.Sheets(G).Range("a2", Wb.Sheets(G).Cells.SpecialCells(xlCellTypeLastCell)).Copy .Cells(.Range("A65536").End(xlUp).Row + 1, 1)
End If
.UsedRange.Rows.AutoFit
.UsedRange.Columns.AutoFit
End With
End If
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
' 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

VBA也可以很方便的实现文件操作。本文主要实现当文件夹不存在时，自动创建文件夹的功能。

假设我们要实现的功能是在D盘根目录下创建vbatest文件夹，可以看到，当前文件夹是不存在的：



我们在vb代码编辑器里输入下面的代码：
Sub dir()
    Dim myDir As String
    myDir = "D:\vbatest"
    On Error Resume Next
    mkdir myDir
End Sub

按F5执行，即可成功创建 文件夹，如下图所示：
