[原创]VBA实现汇总excel，将多个Excel文件内容复制到一个Excel文件中

功能：遍历用户指定的文件夹，把文件夹中所有的excel文件的第一个表格的数据复制到本excel文件中。注意，每个excel文件中有效数据行的判断标准是A列的最后一个有数据的单元格的行号，比如A列到第10行结束，B列到第11行结束，那么程序将不会复制第11行。

说明：鄙人也不是大闲人，也就没有去迎合各种需求，只是根据自己的需要去写的，拿出来分享一下。

闲话少说，直接上代码，复制到宏命令代码里面，执行combine宏即可实现。

Sub combine()
    Dim folder As String
    Dim count As Integer
        
    folder = ChooseFolder()
    
    count = combineFiles(folder, "xls")
    'count = count + combineFiles(folder, "xlsx")

End Sub

'整合文件
Function combineFiles(folder, appendix)
    Dim MyFile As String
    Dim s As String
    Dim count, n, copiedlines As Integer
    
    MyFile = Dir(folder & "*." & appendix)
    count = count + 1
    n = 2
    Do While MyFile <> ""
        copiedlines = CopyFile(folder & "" & MyFile, 2, n)
        If copiedlines > 0 Then
            n = n + copiedlines
            count = count + 1
        End If
        MyFile = Dir
    Loop
    combineFiles = count
End Function

'复制数据
Function CopyFile(filename, srcStartLine, dstStartLine)

    Dim book As Workbook
    Dim sheet As Worksheet
    Dim rc As Integer
    
    CopyFile = 0
    
    If filename = (ThisWorkbook.Path & "" & ThisWorkbook.Name) Then
        Exit Function
    End If
    
    Set book = Workbooks.Open(filename)
    Set sheet = book.Sheets(1) '使用第一个sheet
    rc = sheet.Range("A65536").End(xlUp).Row
    If rc >= srcStartLine Then
        sheet.Rows(srcStartLine & ":" & rc).copy ThisWorkbook.Sheets(1).Range("A" & dstStartLine) '复制到指定位置
        CopyFile = rc - srcStartLine + 1
    End If
    book.Close

End Function

'选择文件夹
Function ChooseFolder() As String
    Dim dlgOpen     As FileDialog

    Set dlgOpen = Application.FileDialog(msoFileDialogFolderPicker)
    With dlgOpen
        If .Show = -1 Then
            ChooseFolder = .SelectedItems(1)
        End If
    End With
    Set dlgOpen = Nothing
End Function
