Case Converter — Free Text Utility

Case Converter switches text between every common casing style in one click — UPPERCASE, lowercase, Title Case, Sentence case, tOGGLE cASE, camelCase, PascalCase, snake_case, and kebab-case — saving the tedious manual retyping needed when content needs to match a specific style guide or programming convention. Writers commonly need Title Case for headlines, Sentence case for cleaning up text pasted from all-caps sources, and developers regularly need to convert human-readable labels into camelCase or snake_case variable names. Rather than manually retyping or using error-prone find-and-replace tricks, paste your text once and pick the exact casing style you need.
