Question

我运行Python XLWings代码，顺序调用多个Excel文件。虽然代码在处理后关闭每个Excel（并且在任何给定时刻不超过1个excel），但该过程变得越来越慢。内存测试显示关闭excel文件后剩余进程仍然存在。

有更顺畅的方法吗？也许XLWings可以在后台模式下调用这些Excel文件，而无需花时间和内存加载界面吗？

感谢您的帮助。

是的，USE [NileTraveltest] GO /****** Object: Table [dbo].[DayDetails] Script Date: 23/07/2017 1:46:54 PM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[DayDetails](

简单示例：

visible=False

xlwings可以在后台运行excel吗？
