A case converter is a tool that instantly transforms the capitalisation style of any text. Whether you need to convert a heading to Title Case, format a variable name in camelCase for JavaScript, or turn all caps into sentence case, this tool handles it in one click.
This converter supports 10 common text case formats used in writing, programming, and design: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, SCREAMING_SNAKE_CASE, kebab-case, and aLtErNaTiNg CaSe.
camelCase joins words without spaces, capitalising each word after the first. Used widely in JavaScript and Java variable names (e.g. myVariableName).
snake_case uses underscores between words with all letters lowercase. Common in Python, Ruby, and database column names.
Title Case capitalises the first letter of each major word. Used in headings, book titles, and article headlines.
kebab-case uses hyphens between lowercase words. Popular in URLs, CSS class names, and HTML attributes.
