MD vs DOCX

Compare Markdown and Microsoft Word formats — understand the key differences and when to use each

Format Overview

MD

Markdown

MD (Markdown) is a lightweight markup language created by John Gruber in 2004. Markdown uses plain text formatting syntax (#, *, -, etc.) that converts to HTML. It's the standard format for README files, documentation, technical writing, and note-taking. Markdown is used by GitHub, GitLab, Stack Overflow, Reddit, Discord, and thousands of other platforms. Various flavors exist including CommonMark, GitHub Flavored Markdown (GFM), and MultiMarkdown.

DOCX

Microsoft Word

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.
