Sobre los archivos HTMLComparativa de ventajas
DOCX Ventajas
- 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.
HTML Ventajas
- Universal — every browser, OS, email client, and document reader displays HTML.
- Plain text, human-readable, grep-able, and diffable in git.
- Flexible — pages render even with broken or partial markup (error-tolerant parser).
- Carries structure, styling (CSS), and behavior (JavaScript) in one file.
- Accessibility-friendly when written with semantic tags and ARIA attributes.
Limitaciones
DOCX Limitaciones
- 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.
HTML Limitaciones
- Error tolerance allows sloppy markup to hide real bugs.
- Rendering depends on browser engine — pixel-perfect cross-browser output is an art form.
- Security-sensitive — unsafe HTML can execute scripts or leak data (XSS vulnerabilities).
- File size for equivalent structured data is larger than JSON or XML due to tag verbosity.
- No built-in typing or schema — contract between server and client is informal.
