Transformed = CaseTransform(Input, Mode)Worked Example: Headline Title Casing
Convert an unformatted lowercase draft string into an editorial headline.

target Case:Title Case
Expected OutputThe Quick Brown Fox Jumps Over a Lazy Dog
Capitalizes major nouns and verbs while preserving minor prepositions and articles.
Technical Constraints & Limitations
- Proper names that violate standard grammatical casing rules (e.g., iPhone, eBay, mRNA) should be reviewed manually.
- Sentence casing relies on standard terminal punctuation marks (. ! ?) to detect clause boundaries.
Frequently Asked Questions
What is the difference between Title Case and Capitalized Case?
Title Case keeps minor grammatical words (like "a", "an", "the", "in", "of") lowercase unless they begin the sentence. Capitalized Case capitalizes the first letter of every single word unconditionally.
Does this converter preserve non-English accents and diacritics?
Yes. The engine uses modern ECMAScript Unicode properties to preserve accents (such as é, ñ, ç, and ö) across all transformations.
