The Text Case Converter transforms pasted text into the casing styles exposed by the component, such as uppercase, lowercase, sentence case, and title case.

Limitations

Case rules vary by language, acronym, punctuation, and brand name. Review title case output manually before publishing.

Method

Uppercase and lowercase modes apply the component's Unicode-aware case conversion. Sentence and title modes detect word boundaries and punctuation, then capitalize selected characters. Preserve original text when names, acronyms, code, URLs, or non-English text need review.

Example

“the quick BROWN fox.” becomes “THE QUICK BROWN FOX” in uppercase, “the quick brown fox.” in lowercase, and “The quick brown fox.” in sentence case. Title-case treatment of short connecting words depends on the tool's rules.

Interpretation

Case conversion changes presentation, not grammar or meaning. It does not proofread spelling, expand acronyms, or understand brand capitalization.

Common questions

Is title case suitable for every language?

No. Capitalization conventions vary, so manually review multilingual and branded text.

Can I use it on code?

Only when the identifier is not case-sensitive; changing code tokens can break behavior.
