Why this happens
Capitalization issues are typically introduced when text comes from:
- PDFs or slide decks (often ALL CAPS or Title Case)
- mixed collaborators using different styles
- AI drafts that mix heading/body capitalization
- copying between email clients and docs
When you standardize case, you improve readability and reduce “visual noise.” Hub: /blog/case-conversion-and-formatting-hub/.

- Skim headings separately to match your style guide.
Common mistakes
- Converting headings and body together
- Losing acronyms (API → Api)
