DOCX vs ORG
Word Document と Org-mode を徹底比較 — ファイルサイズ、品質、互換性、そして用途に応じた最適なフォーマットの選び方を解説します。
Word Document
Documents & TextDOCX is the modern Microsoft Word format based on Open XML. It is the most widely used word processing format in business and education, supporting rich text, images, tables, and macros.
DOCX ファイルについてOrg-mode

ORG ファイルについて長所の比較
DOCX 長所
- Much smaller than the legacy .doc format thanks to ZIP compression.
- Human-readable XML inside — automated extraction and manipulation is straightforward.
- Preserves formatting, images, tables, footnotes, comments, and track changes.
- Supported natively by Word, LibreOffice, Pages, Google Docs, and most modern editors.
- ISO/IEC 29500 standardized — not locked to a single vendor.
ORG 長所
- All-in-one productivity format — tasks, notes, agenda, papers.
- Plain UTF-8 text — diff-friendly, version-controllable.
- Literate programming with tangle/weave.
- Exports to HTML, PDF, LaTeX, ODT, Markdown, Beamer.
- Active open-source community with decades of extensions.
制限・弱点
DOCX 制限・弱点
- Subtle formatting drifts when opened in non-Microsoft editors (fonts, line spacing, tab stops).
- Macros and embedded scripts make older .docm variants a common malware vector.
- Complex layouts with floating objects often reflow unpredictably.
- Version compatibility matters — Word 2007 cannot open some Word 2019 features cleanly.
ORG 制限・弱点
- Emacs-centric — full power requires Emacs; other editors see syntax but miss features.
- Steep learning curve alongside Emacs itself.
- Limited mobile support (Orgzly on Android is the main option).
- Power comes from ecosystem, not format — not portable to Notion/Obsidian cleanly.
