如何将一个文件夹中的多个文件复制到一个电子表格中？

Question

我刚开始使用excel宏。我的问题是，我有一个文件夹中的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完成的事情吗？任何帮助表示赞赏。请参阅我录制的VBA代码。我如何修改这个来实现我的目标？

    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。

您必须更正您的路径（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

这可以在电源的查询来完成与丝带图标只需点击几下。不需要VBA。

从文件启动一个新的查询

• 导航到文件夹
• 选择所有文件
• 删除文件不带过滤器的需要（可选步骤）
• 结合二进制
• 选择你想保留的列

如果文件夹中的文件发生更改，只需刷新查询即可。

Power Query是Microsoft为Excel 2010和2013提供的一个免费加载项，并且内置到Excel 2016中，如获取& Transform。

试试这个方法。

    'Fill in the path\folder where the files are 
    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*")
