Docx4j functionality to turn a document into JSON representation?

Is there a good way to convert a document into JSON representation to then display on a web page? (It is a requirement that the document is converted to JSON)

My Idea if there isn't a built in way to do this is to represent the Run/Paragraph structure as JSON Objects, but I feel like this wouldn't work as well once I start working with more complex Word Documents.

If you add:

<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-xml</artifactId>
<version>2.11.3</version>
</dependency>

you can try something like:

import org.docx4j.Docx4J;
import org.docx4j.openpackaging.packages.WordprocessingMLPackage;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
public class ConvertOutJSON  {
static String inputfilepath = System.getProperty("user.dir") + "/sample-docs/sample-docxv2.docx";
public static void main(String[] args)
throws Exception {
WordprocessingMLPackage wordMLPackage 
= Docx4J.load(new java.io.File(inputfilepath));
String xml = wordMLPackage.getMainDocumentPart().getXML();
//System.out.println(xml);
XmlMapper xmlMapper = new XmlMapper();
JsonNode node = xmlMapper.readTree(xml);
ObjectMapper jsonMapper = new ObjectMapper();
//String json = jsonMapper.writeValueAsString(node);
String json = jsonMapper.writerWithDefaultPrettyPrinter().writeValueAsString(node);
System.out.println(json);
}    
}

However in a quick test, I noticed some w:p nodes were not being emitted as JSON. I haven't looked to see whether they get dropped by Jackson at the readTree step or when ObjectMapper writes its output; you'll need to dig into Jackson to fix that.

It is currently producing output like:
