OpenXML is the standard used for Office documents.
You can think of it as a .zip in a trenchcoat.
Every part of an Excel, PowerPoint, or Word document is saved into an archive.
You can prove this to yourself by renaming any .docx file to .zip.
I sometimes call this the "zip epiphany", because it helps you understand how much technology is really a "zip in a trenchcoat".
(hint: it's much more than just OpenXML files)
This module is here to help you automate, inspect, and understand OpenXML files.

It has a large amount of room to grow.
The primary goal for the forseeable future is to increase coverage of office features. If you would like to help, please consider contributing.
