Question

对于客户端，我需要修改数百个Excel电子表格中包含的VBA代码 - 某些dll调用需要替换为对另一个库的调用。

有没有办法编写打开电子表格的程序（VB，.NET，java ...），查看包含的VBA，应用必要的修改并保存？

您可以编写VBA程序来自动执行代码更改过程

在工具中 - ＆gt;参考

添加：Microsoft Visual Basic For Applications Extensibility X.Y

下面是我编写的一些代码，用于将代码添加到ThisWorkbook Module中关键功能是

InsertLines

行

DeleteLines
