DOCX is the modern Microsoft Word document format, introduced with Office 2007 and based on the Office Open XML (OOXML) standard (ISO/IEC 29500). Internally, a DOCX file is a ZIP archive containing XML files that define content, styles, relationships, and metadata. DOCX supports rich text formatting, styles and themes, tables, images, charts, SmartArt, mathematical equations, content controls, tracked changes, comments, headers/footers, footnotes, and bibliographies. The XML-based structure makes DOCX files smaller than DOC, more reliable for cross-platform use, and easier to process programmatically. DOCX is the standard document format for business, education, and publishing. It's natively supported by Microsoft Word, Google Docs, LibreOffice, and Apple Pages.
