用python批量执行VBA代码

先说下背景环境

　　1. 公司需要问卷调查，有两份问卷， 1）是spss问卷，2）是excel问卷。spss问卷数据不全，但有各种标签， excel呢， 生成的数据直接把选项变成了值

　　2. 现在需要把excel的选项值变成1， 2这种数字{1：“满意”}

　　3. 妹子已经把vba写好了。（不忍直视！）

由于需要执行很多vba命令，我就用py的字符串拼接，生成了，900多份，怀疑vba的代码有问题，凭直觉，但我不会vba，又懒得查，只能让cpu去做重复工作了

需要模块win32com

安装方法

```

python3 -m pip install pypiwin32

```

生成vba命令

用Python在执行vba命令方法，有点类似执行shell的形式，但必须在windows环境下面执行，不能在linux下面

注意问题：

　　. 必须另存为xlsm文件格式

　　. 第二，在执行Python脚本的时候必须是打开excel的

　　. 必须新建模块（vba中）

　　. vba代码必须有函数

　　. office必须开启宏，否则不生效
　　6. 打开vba快捷键alt + f11

最后看代码

vba代码

Sub test()    《============这个函数很重要，对应着python
Dim m
m =
Columns("G:G").Select
m =
On Error GoTo Err_Handle

For m =  To
Selection.Find(What:="男", After:=ActiveCell, LookIn:=xlFormulas, LookAt _
:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
False, MatchByte:=False, SearchFormat:=False).Activate
ActiveCell.Replace What:="男", Replacement:="", LookAt:=xlPart, _
SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
ReplaceFormat:=False
Next m

Exit Sub
