Convert word to html document using java
1 Introduction
Recently, due to project needs, I need to parse and split word documents. I feel that parsing word directly is a bit troublesome, so I thought that it would be more convenient to convert word to html document first, and then use jsoup to parse the html file. For the use of jsoup, you can refer to the relevant API. The operation is simple, similar to javascript.
The method to convert word to html document is as follows:
Generally, the suffixes of word files are doc and docx. Docx is the extension for documents of Office Word 2007 and later versions; doc is the extension for documents saved in Office Word 2003. Different methods are required to convert word to html in these two formats.
2. Add dependencies

Use poi to convert documents in docx format. The dependencies are as follows:
