About Case Converter
Case Converter switches text between nine case styles — UPPER, lower, Title, Sentence, camelCase, PascalCase, snake_case, kebab-case, and aLtErNaTiNg. Conversion is pure in-browser string manipulation — no upload, runs as you click.
Title Case capitalizes every word's first letter (no exceptions for the, of, etc.). Sentence case only capitalizes the first letter after each sentence break. The programming-style cases (camel, Pascal, snake, kebab) all use the same word-boundary detection — spaces, hyphens and underscores split words — so you can paste any source format and switch freely between them.
