Question

我刚开始使用excel宏。我的问题是我在一个文件夹中有500个excel文件。我正在寻找一种方法将这500个文件中的每一个的第一列和第二列复制到一个电子表格中。这是可以使用excel VBA完成的事情。任何帮助表示赞赏。请参阅我录制的VBA代码。如何修改它以实现我的目标？

    ActiveCell.Range("A1:B1").Select
    Range(Selection, Selection.End(xlDown)).Select
    Selection.Copy
    Windows("Book1").Activate
    ActiveSheet.Paste
End Sub

请在代码中阅读我的评论。

您必须更正路径（地址），文件夹名称和文件名。

Option Explicit

Sub LoopAllFiles()
Dim myCalc As XlCalculation
Application.EnableCancelKey = xlDisabled
Application.ScreenUpdating = False
Application.Calculation = myCalc
Application.Calculation = xlCalculationManual
Dim folderPath As String
Dim Filename As String
Dim wb As Workbook, wbMaster As Workbook
Dim sh As Worksheet
Dim ColNo As Long
    ColNo = 1
folderPath = "C:\testfolder\" 'contains folder path
'or folderPath = "C:\Users\AshleyLarson\Desktop\LoopThroughFolders\AnyFolder\" 
' ==> Please correct your path otherwise code won't work. <==
If Right(folderPath, 1) <> "\" Then folderPath = folderPath + "\"
Filename = Dir(folderPath & "*.xlsx")
Do While Filename <> ""

    Set wb = Workbooks.Open(folderPath & Filename)
    Set wbMaster = Workbooks.Open(folderPath & "masterfolder\Master Template.xlsx")   ' BE CAREFUL This should be your Master File's path

    wb.Sheets(1).Range("A1:B" & (Range("A" & Rows.Count).End(xlUp).Row) + 100).Copy

    Workbooks("Master Template").Worksheets("Sheet1").Range(Chr(ColNo + 64) & ":" & Chr((ColNo + 1) + 64)).PasteSpecial xlPasteValues
    ColNo = ColNo + 2
    Application.DisplayAlerts = False
    Workbooks(Filename).Save
    Workbooks(Filename).Close
    Workbooks("Master Template.xlsx").Save
    Workbooks("Master Template.xlsx").Close
    Application.DisplayAlerts = True
    Filename = Dir
Loop
   Application.ScreenUpdating = True
   Application.Calculation = myCalc
End Sub

Answer 2

只需点击功能区图标，即可在Power Query中完成此操作。不需要VBA。

开始新的查询

来自档案
导航到文件夹
选择所有文件
删除过滤器不需要的文件（可选步骤）
合并二进制文件
选择要保留的列

如果文件夹中的文件发生变化，只需刷新查询。

Power Query是Microsoft for Excel 2010和2013的免费插件，内置于Excel 2016中作为Get＆amp;转变。

以这种方式试试。

    MyPath = "C:\Users\Ron\test"

    'Add a slash at the end if the user forget it
    If Right(MyPath, 1) <> "\" Then
        MyPath = MyPath & "\"
    End If

    'If there are no Excel files in the folder exit the sub
    FilesInPath = Dir(MyPath & "*.xl*")
