UPPER for constants and headings; Title Case for document titles; camelCase for JavaScript variables; snake_case for Python/files; kebab-case for URLs and CSS classes. Pick by ecosystem convention, not taste.
Articles and short prepositions (a, the, of, in) stay lowercase mid-title per Chicago/AP style — the converter follows standard title-casing rules, not naive capitalize-every-word.
camelCase starts lowercase (myVariable) for variables/functions; PascalCase starts uppercase (MyClass) for classes/components. The converter offers both — check your language's convention.
Yes — pastes of full articles convert instantly since it's pure string ops. Sentence case on long text: verify abbreviations (e.g., 'e.g.') didn't trigger false sentence breaks.
No. Conversion runs entirely in your browser. Text never leaves your device.
Seven rows at once: UPPER, lower, Title, camelCase, snake_case, kebab-case, and UPPER_SNAKE. Title capitalizes every word (‘of mice and men’ becomes ‘Of Mice And Men’ — small words aren’t excepted), and words split on letters/digits, so ‘hello-world_test’ becomes helloWorldTest. Press Convert — it isn’t automatic.
