python 通过直接操控窗口实现开票软件的快速辅助输入工具。

背景: 深增值税开票软件在填入发票的明细时(2016年),没有从exce导入的功能,只能手工一个一个输入,对于明细清单数量多的情况,给财务人员带来过多的工作量。所以考虑做一个辅助输入工具。减轻财务的工作量,降低手工输入的出错率。

 

思路如下: 发票清单 Excel 格式如下, 因为开票的清单来自于销售的出货清单,都是excel格式(从sap导出的),处理起来很方便,所以也延续用Excel格式。

软件功能需要,实现将上面的清单,自动填入到,深增开软件的 清单填开 表格内。 实现原理也很简单,用程序来模拟手工输入过程,控制光标移动。 同一客户,可以连续打印发票。

选好 excel文件,然后层入。看以下效果图:

完整代码如下。用了pywin32 来操作窗口,完成光标移动,数据输入。
