How the transforms work
UPPERCASE and lowercase use your browser's own locale-aware casing. Title Case lowercases the text and capitalizes the first letter of each word; Capitalize Each Word only changes the first letter of each word and leaves the rest exactly as typed. Sentence case capitalizes the first letter of each sentence, using the same sentence-boundary rules built into your browser (a period followed by a lowercase word, as in an abbreviation, may not start a new sentence). camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE split words the same way regardless of spaces, hyphens, underscores or letter-case boundaries (e.g. "XMLHttpRequest" → "xml_http_request").
What this tool does
Change text between sentence case, title case, camelCase, snake_case, and more.
Before you start
Acronyms and brand names may need a final human check because casing rules cannot infer every proper noun.
