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.
