## Description

Open-XML-SDK is a library for programmatically creating, modifying, and validating Office documents based on the Open XML standard. It functions as an office file generator and XML document parser, enabling the manipulation of word processing, spreadsheet, and presentation files.

The library allows for the generation and updating of document content and structure without requiring the native office applications to be installed. It utilizes strongly typed classes and a schema-validated approach to ensure that created files remain compatible and correctly structured.

The project provides capabilities for structural validation against official schemas, the embedding of multimedia content such as video, and the management of document parts and relationships. It supports both in-memory tree manipulation and stream-based parsing for processing document data.
