通过VBA宏合并Excel工作表

工作中经常会用到的把几个Excel文件合并到一个，或者是把一个Excel文件里的所有Sheet合并到一个Sheet来进行统计。下面分别提供用vba宏来解决这两个问题的方法。

1、合并Excel文件

打开一个空Excel文件，Alt+F11，插入一个模块，开始写代码：

Sub MergeWorkbooks()
    Dim FileSet
    Dim i As Integer
   
    On Error GoTo 0
    Application.ScreenUpdating = False

    FileSet = Application.GetOpenFilename(FileFilter:="Excel 2003(*.xls),*.xls,Excel 2007(*.xlsx),*.xlsx", _
                                            MultiSelect:=True, Title:="选择要合并的文件")
   
    If TypeName(FileSet) = "Boolean" Then
        GoTo ExitSub
    End If
   
    For Each Filename In FileSet
        Workbooks.Open Filename
        Sheets().Move After:=ThisWorkbook.Sheets(ThisWorkbook.Sheets.Count)
    Next
   
ExitSub:
    Application.ScreenUpdating = True
   
End Sub

这段代码的作用：它首先打开一个文件选择框，你可以选择一个或多个文件，然后把这些文件里的所有Sheet合并到当前这个工作簿里来，有重名的Sheet会自动在后面加数字。

2、合并一个EXCEL多个sheet的内容到一个汇总sheet

同上，再添加一个模块吧，代码如下：

Function LastRow(sh As Worksheet)
    On Error Resume Next
    LastRow = sh.Cells.Find(what:="*", _
                            After:=sh.Range("A1"), _
                            Lookat:=xlPart, _
                            LookIn:=xlFormulas, _
                            SearchOrder:=xlByRows, _
                            SearchDirection:=xlPrevious, _
                            MatchCase:=False).Row
    On Error GoTo 0
End Function

Sub MergeSheets()
    Dim sh As Worksheet
    Dim DestSh As Worksheet
    Dim Last As Long
    Dim shLast As Long
    Dim CopyRng As Range
    Dim StartRow As Long

    Application.ScreenUpdating = False
    Application.EnableEvents = False

    '新建一个“汇总”工作表
    Application.DisplayAlerts = False
    On Error Resume Next
    ActiveWorkbook.Worksheets("汇总").Delete
    On Error GoTo 0
    Application.DisplayAlerts = True
    Set DestSh = ActiveWorkbook.Worksheets.Add
    DestSh.Name = "汇总"

    '开始复制的行号，忽略表头，无表头请设置成1
    StartRow = 2

    For Each sh In ActiveWorkbook.Worksheets

        If sh.Name <> DestSh.Name Then
            Last = LastRow(DestSh)
            shLast = LastRow(sh)

            If shLast > 0 And shLast >= StartRow Then

                Set CopyRng = sh.Range(sh.Rows(StartRow), sh.Rows(shLast))

                If Last + CopyRng.Rows.Count > DestSh.Rows.Count Then
                    MsgBox "内容太多放不下啦！"
                    GoTo ExitSub
                End If

                CopyRng.Copy
                With DestSh.Cells(Last + 1, "A")
                    .PasteSpecial xlPasteValues
                    .PasteSpecial xlPasteFormats
                    Application.CutCopyMode = False
                End With
            End If
        End If
    Next

ExitSub:
    Application.GoTo DestSh.Cells(1)
    DestSh.Columns.AutoFit
    Application.ScreenUpdating = True
    Application.EnableEvents = True
   
End Sub

这段代码的作用：它会新建一个叫做“汇总”的工作表，然后把当前工作簿里的所有Sheet里有数据的内容都复制到“汇总”表里。提示：如果数据表里的内容没有表头的话需要把StartRow = 2改成StartRow = 1。
