首先，按键盘上的Alt+F11进入VBA代码编辑界面。

在工作簿中插入一个模块。代码如下：

Sub SaveAs()

    On Error Resume Next

    Dim FolderPath As String, FolderName As String, BN As String

    Dim ReturnValue As Integer

    BN = ActiveWorkbook.Name

    FolderPath = ThisWorkbook.Path

    FolderName = Mid(BN, 1, InStrRev(BN, ".", Len(BN)) - 1)

    Dim MyFile As Object

    Set MyFile = CreateObject("Scripting.FileSystemObject")

    If MyFile.folderexists(FolderPath & "\" & FolderName & "-Saved") Then

        ReturnValue = MsgBox("文件夹已存在，是否更新内容？", vbOKCancel, "Caution!")

        If ReturnValue = 2 Then Exit Sub

    Else

        MyFile.CreateFolder (FolderPath & "\" & FolderName & "-Saved")

        Set MyFile = Nothing

    End If

    Application.ScreenUpdating = False

    Application.DisplayAlerts = False

    Dim i As Integer

    For i = 1 To Sheets.Count

        Set Wk = Workbooks.Add

        Workbooks(BN).Sheets(i).Copy before:=Wk.Worksheets("Sheet1")

        Wk.SaveAs FolderPath & "\" & FolderName & "-Saved\" & ThisWorkbook.Sheets(i).Name

        Wk.Close

    Next i

    Application.DisplayAlerts = True

    Application.ScreenUpdating = True

End Sub

插入一个按钮并指定按钮至刚才插入的宏代码

点击刚才插入的按钮，运行完毕后可以看到在同目录下出现了一个名称为“拆分工作表-Saved”文件夹，打开文件夹可以看到被拆分出来的若干个工作表。
