About text case conversion
Different contexts want different casing: prose uses Sentence case, headings use Title Case, code uses camelCase, snake_case or kebab-case, and slugs and constants have their own conventions. Retyping to switch between them is slow and error-prone.
This converter applies any of seven common case styles instantly as you type, so you can reformat a heading, a variable name or a whole paragraph in one step and copy the result. Everything runs in your browser — nothing is uploaded.
