How to Change Text Case (UPPERCASE, lowercase, Title Case)
Retyping a sentence because Caps Lock was on, or hand-capitalizing every word in a title, is wasted effort. Case conversion fixes any block of text in one click — switching between uppercase, lowercase, title case, and more without touching the words themselves.
The common case styles
- UPPERCASE — every letter capital, for emphasis or headings.
- lowercase — every letter small, to undo an accidental Caps Lock.
- Title Case — Each Major Word Capitalized, for headlines and titles.
- Sentence case — Only the first word and proper nouns capitalized.
Developer case styles
If you write code, you'll also meet camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE — naming conventions for variables, files, and constants. Converting a phrase straight into the right style saves fiddling with capitals and separators by hand.
