在多个Excel文件中合并来自类似工作表的数据

Question

我有数百个MS Excel文件，每个文件都有多个工作表，在特定文件夹下的结构和模式类似。每种类型的工作表都有以下结构（列的范围可能不同）; 例如部门工作表可能看起来像这样

Column A  | Column B  | Column C 

Header A  | Header B  | Header C

[value]   |  [value]  |  [value]

我想将多个excel文件中的所有部门工作表合并到一个大的离开工作表中，例如

Column A  | Column B  | Column C 

Header A  | Header B  | Header C

[value]   |  [value]  |  [value]
[value1]      |  [value1]  |  [value1]
[value2]      |  [value2]  |  [value2]
[value3]      |  [value3]  |  [value3]... 

这样做的自动化方式是什么？谢谢。

这样的事情应该非常接近。

Sub Basic_Example_1()
    Dim MyPath As String, FilesInPath As String
    Dim MyFiles() As String
    Dim SourceRcount As Long, Fnum As Long
    Dim mybook As Workbook, BaseWks As Worksheet
    Dim sourceRange As Range, destrange As Range
    Dim rnum As Long, CalcMode As Long

    '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*")
    If FilesInPath = "" Then
        MsgBox "No files found"
        Exit Sub
    End If

    'Fill the array(myFiles)with the list of Excel files in the folder
    Fnum = 0
    Do While FilesInPath <> ""
        Fnum = Fnum + 1
        ReDim Preserve MyFiles(1 To Fnum)
        MyFiles(Fnum) = FilesInPath
        FilesInPath = Dir()
    Loop

    'Change ScreenUpdating, Calculation and EnableEvents
    With Application
        CalcMode = .Calculation
        .Calculation = xlCalculationManual
        .ScreenUpdating = False
        .EnableEvents = False
    End With

    'Add a new workbook with one sheet
    Set BaseWks = Workbooks.Add(xlWBATWorksheet).Worksheets(1)
    rnum = 1

    'Loop through all files in the array(myFiles)
    If Fnum > 0 Then
        For Fnum = LBound(MyFiles) To UBound(MyFiles)
            Set mybook = Nothing
            On Error Resume Next
            Set mybook = Workbooks.Open(MyPath & MyFiles(Fnum))
            On Error GoTo 0

            If Not mybook Is Nothing Then

                On Error Resume Next

                With mybook.Worksheets(1)
                    Set sourceRange = .Range("A1:C1")
                End With

                If Err.Number > 0 Then
                    Err.Clear
                    Set sourceRange = Nothing
                Else
                    'if SourceRange use all columns then skip this file
                    If sourceRange.Columns.Count >= BaseWks.Columns.Count Then
                        Set sourceRange = Nothing
                    End If
                End If
                On Error GoTo 0

                If Not sourceRange Is Nothing Then

                    SourceRcount = sourceRange.Rows.Count

                    If rnum + SourceRcount >= BaseWks.Rows.Count Then
                        MsgBox "Sorry there are not enough rows in the sheet"
                        BaseWks.Columns.AutoFit
                        mybook.Close savechanges:=False
                        GoTo ExitTheSub
                    Else

                        'Copy the file name in column A
                        With sourceRange
                            BaseWks.cells(rnum, "A"). _
                                    Resize(.Rows.Count).Value = MyFiles(Fnum)
                        End With

                        'Set the destrange
                        Set destrange = BaseWks.Range("B" & rnum)

                        'we copy the values from the sourceRange to the destrange
                        With sourceRange
                            Set destrange = destrange. _
                                            Resize(.Rows.Count, .Columns.Count)
                        End With
                        destrange.Value = sourceRange.Value

                        rnum = rnum + SourceRcount
                    End If
                End If
                mybook.Close savechanges:=False
            End If

        Next Fnum
        BaseWks.Columns.AutoFit
    End If

ExitTheSub:
    'Restore ScreenUpdating, Calculation and EnableEvents
    With Application
        .ScreenUpdating = True
        .EnableEvents = True
        .Calculation = CalcMode
    End With
End Sub

另外，请看这个。

如果要将所有单元格从工作表或从A2复制到工作表上的最后一个单元格。然后用此替换上面的代码

With mybook.Worksheets(1)
    FirstCell = "A2"
    Set SourceRange = .Range(FirstCell & ":" & RDB_Last(3, .Cells))
    'Test if the row of the last cell >= then the row of the FirstCell
    If RDB_Last(1, .Cells) < .Range(FirstCell).Row Then
         Set SourceRange = Nothing
    End If
End With
