Case Converter
Paste your text and switch it between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case and kebab-case with one click. Everything happens in your browser.
Text cases and when to use them
Different contexts call for different casing: Title Case for headings, Sentence case for body copy, UPPERCASE for emphasis or constants. Getting there by hand is tedious, especially for long text.
The programmer cases are just as handy — camelCase for JavaScript variables, snake_case for Python and databases, kebab-case for URLs and CSS classes. Convert between them in one click; everything runs locally.
