About the product
Simple Case Converter fixes letter case without retyping. Paste text and switch it to Sentence case, lower case, UPPER CASE, Capitalized Case, Title Case, aLtErNaTiNg or InVeRsE in one click. Title Case follows the style guide you pick, AP, APA, Chicago or MLA, because they disagree about short words such as "with" and "of".
For developers it also produces camelCase, PascalCase, snake_case, SCREAMING_SNAKE_CASE, kebab-case, dot.case and URL slugs. Locale options (for example Turkish and German) handle letters that change differently between languages, and a smart proper-noun option keeps names capitalised in sentence case.
Text is processed in your browser and nothing is uploaded or stored. Beyond case conversion, the site has extra text utilities: cleanup tools, word and character counters, Unicode social-media fonts, small caps and developer converters such as JSON, CSV and YAML. Free, no signup, in 14 languages.
