研究了很多网上的文章，实际上并没有什么作用，尤其是后端对文档的处理，网上的都是开源的jar包处理，转换后要么乱码，要么样式乱，根本达不到自己想要的效果，想过对接wps平台；没想到接口收费那么贵，1页/0.1元，那随便一个文档转换下来100页还不得10元吗？不现实；
还是老外开发的靠谱，最后对接了这个网站，100页就0.3-0.5元的成本而已，而且效果非常好
先看效果：pdf-wrod-excel相互转换
对接的文档转换api: https://cloudconvert.com/pdf-to-docx，如果英文不太好不容易理解的，也可以直接对接：pdf-wrod-excel相互转换API接口
流程：前端上传文档file流给后端，后端调用第三方接口直接处理即可，第三方会返回文档链接
java代码如下
