How the text is processed
Case conversion applies Unicode-aware letter casing and mode-specific capitalization rules. Title and sentence case are editorial transformations, so acronyms and proper names may still need review.
Useful workflows
- Normalize headings and labels
- Clean text copied from all-caps sources
- Prepare consistent identifiers or test data
Limits and review checks
- Automatic title case cannot know every proper noun or house style.
- Some languages have locale-specific casing rules.
- Case conversion does not correct spelling, punctuation or grammar.
Frequently asked questions
Why is a small word capitalized in title case?
Title-case conventions differ by style guide; review articles, conjunctions and prepositions after conversion.
Does uppercase conversion remove accents?
No. Letter case changes while supported accents and other characters are retained.
