Office Open XML

Office Open XML is a standardized format used by Microsoft Office programs like Word, Excel, and PowerPoint to save documents. It organizes a file’s content—including text, images, styles, and formatting—as a collection of structured data within a compressed package, typically a ZIP file. This format allows documents to be easily created, shared, and edited across different platforms and software, while maintaining consistent appearance and features. Essentially, Office Open XML ensures that your documents are stored in a clear, organized, and open way, enabling better interoperability and future-proofing.
