在Python中从.docx文件中的表中提取Acrobat文档对象

我有一个.docx文件，里面有一个表。有些单元格包含嵌入的Acrobat文档对象

我正在使用

python docx

模块从.docx文件中读取和提取数据，但它没有获取那些嵌入的文档（当要求输入单元格值时，它返回一个空字符串）

由于我认为自己不够好，无法尝试修改模块源代码，所以我曾想过从.docx文件本身提取嵌入文档（通过[将扩展名更改为.zip][1]），但pdf文件似乎是.bin格式

所以我在考虑四种可能的解决方案，你们可以帮我：

获取

python docx

模块以识别嵌入的Acrobat文档对象

让Python将.bin文件转换为pdf

也许可以向我推荐另一个Python模块，它可以从.docx文件中提取表（显然还有它的数据），并且还支持Acrobat文档对象

（我不太喜欢的那一个）我看过一些Visual Studio或宏代码（不确定是什么，我会在最后粘贴），据说这些代码在提取pdf嵌入文件时非常有效。问题是我并不真正喜欢VisualStudio的东西，所以我需要帮助从Python执行宏（使用简单的语言，并且记住我不是VisualStudio专家）

方法必须使用Python（或另一种不太复杂的自动化方法）完成，因为此过程必须多次执行，并且完全放弃手动提取

事先非常感谢

我在Internet上看到的Visual Studio代码（复制粘贴）：
