Office Open XML Overview

Office Open XML is an open standard (ISO/IEC 29500, ECMA-376 Edition 2) for word-processing documents, presentations, and spreadsheets that can be freely implemented by multiple applications on multiple platforms. Its publication benefits organizations that intend to implement applications capable of using the format, commercial and governmental entities that procure such software, and educators or authors who teach about the format. Ultimately, all users enjoy the benefits of an XML standard for their documents, including stability, preservation, interoperability, and ongoing evolution.
