调用

    Dim xlApp As Object
    Dim excelFilter As String
    Dim excelISAM As String

    '后期绑定Excel对象 不需要知道系统安装的是哪个版本的Excel
    '不需要引用Excel
    If CreateExcelObject(xlApp, excelISAM, excelFilter) = False Then
    	MsgBox "本机未安装Excel或者WPS，导出失败！", vbInformation, "温馨提示"
    End If

异常处理

另外，有时候操作excel会提示 “类 Workbook 的 SaveAs 方法无效”错误。

这个错误通常是电脑同时安装了低版本office excel（如2003）和高版本wps（如最新版2016）导致的。

如果你用保存的代码是

        If xlApp.Version > 11# Then
            xlBook.SaveAs xlsFileName, 51
        ElseIf xlApp.Version <= 11# Then
            xlBook.SaveAs xlsFileName, 56
        End If

请改成，系统会自动帮你保存文件为当前所用 Excel 版本的格式

        If xlApp.Version > 11# Then
            xlsFileName = xlsFileName & ".xlsx"
        ElseIf xlApp.Version <= 11# Then
            xlsFileName = xlsFileName & ".xls"
        End If

        Call xlBook.SaveAs(xlsFileName)
