The .docx format is just a zip file containing multiple .xml files (and sometimes other types) that constitute a given file.

The document content structure is standardized on Office Open XML (https://en.wikipedia.org/wiki/Office_Open_XML).

To explore a .docx file you can unzip it into a folder ie: unzip -d unzipped-folder my_docx.docx

Key files:

document.xml: Contains the main document data. This is usually your starting point.
styles.xml: Contains style definitions, often will be referenced from document.xml
theme/theme1.xml: Contains theme level definitions
