    Dim wB As Workbook
    Dim wS As Worksheet
    Dim fPath As String
    Dim sPath As String
    fPath = "C:UsersqianyDesktop文件"
    sPath = "C:UsersqianyDesktopcsv保存位置"
    fDir = Dir(fPath)
    Do While (fDir <> "")
        If Right(fDir, 4) = ".xls" Or Right(fDir, 5) = ".xlsx" Then
            On Error Resume Next
            Set wB = Workbooks.Open(fPath & fDir)
            'MsgBox (wB.Name)
            For Each wS In wB.Sheets
                wS.SaveAs sPath & wB.Name & ".csv", xlCSV
            Next wS
            wB.Close False
            Set wB = Nothing
        End If
        fDir = Dir
