Case Converter
Switch text between ten different cases without retyping it. As well as the everyday upper, lower, title and sentence cases, it handles the programmer cases — camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE — and understands camelCase input, so it can convert in either direction.

Case Converter — frequently asked questions
Title Case capitalises every significant word — 'The Rise of the Machines'. Sentence case capitalises only the first word of each sentence — 'The rise of the machines'. Most style guides use Sentence case for headings now.
