Common Mistakes to Avoid

Ignoring Proper Nouns in Sentence Case: Sentence case conversions lowercase everything except the first word of a sentence. Make sure to manually capital-correct names, brands, or places after converting.

Confusing Title Case Rules: Short words (like 'and', 'with', 'or') are often lowercased in official editorial style sheets. Double-check your final titles for custom style compliance.

Limitations

Follows standard sentence splitting rules. Some custom formatting or non-standard abbreviations may require manual capitalization review.
