Good to know
Case Converter is the all-in-one tool: choose any of the fourteen cases and the result updates instantly. Letter cases such as UPPER, lower, Title and Sentence only touch capitalisation, while identifier cases like camelCase and snake_case strip punctuation and join real words, so Hello, world! becomes helloWorld or hello_world. Everything runs in your browser and works offline once loaded.
