DOCX Format Hub

Microsoft Word Open XML (.docx) files are the default format for Word documents, encapsulating rich text, styles, tables, and images within a zipped XML package. They support collaboration features like tracked changes and comments. Use sample .docx files to verify import/export fidelity, style mapping, metadata extraction, and co-authoring workflows in desktop and cloud editors.

If this format appears in multiple categories, prefer category-specific hub pages to keep test assumptions aligned with real usage.
