Convert Title Case to Sentence Case Automatically (Without Breaking Meaning)
Scope: converting slide/heading Title Case into sentence case for docs.
TL;DR: Convert messy capitalization into a consistent style (usually sentence case) by converting in plain text first, then restoring acronyms and proper nouns.

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
