How Case Conversion Works
Each case style uses a specific transformation rule:
- UPPERCASE: Every letter is converted to its uppercase form using the Unicode standard.
- lowercase: Every letter is converted to its lowercase form.
- Capitalized Case: The first letter of each word is uppercased and the remaining letters are lowercased. Unlike Title Case, there are no exceptions for minor words.
- Sentence case: The first letter of each sentence is capitalized (detected by periods followed by a space).
- tOGGLE cASE: Each letter's case is flipped — uppercase becomes lowercase and vice versa.
- aLtErNaTiNg cAsE: Letters alternate between uppercase and lowercase, starting with uppercase.
