What Is a Case Converter?
A case converter rewrites text into a different capitalization style — UPPERCASE, lowercase, Title Case, Sentence case, or the programming-style camelCase, PascalCase, snake_case and kebab-case — without retyping a single word by hand.
Writers use it to fix accidentally-capslocked text or format headlines consistently; developers use it to convert a phrase into a valid variable or file name in the naming convention their language or framework expects.
