A case converter changes how letters are capitalised in a piece of text. Writers use it to fix inconsistent capitalisation, developers use it to reformat variable names, and designers use it to prepare display copy for headings and UI labels.
UPPERCASE capitalises every letter. lowercase makes every letter small. Title Case capitalises the first letter of every word, commonly used in article titles and headings. Sentence case capitalises only the first letter of each sentence, matching standard prose style.
camelCase joins words without spaces and capitalises each word after the first, used extensively in JavaScript. PascalCase (UpperCamelCase) capitalises every word including the first, used in class names in C#, Java, and TypeScript. snake_case joins words with underscores and keeps everything lowercase, the standard style in Python. kebab-case joins words with hyphens, used in CSS and URL slugs. CONSTANT_CASE is snake_case in all-caps, used for constants.
Use Title Case for blog post titles, page headings, and product names. Use Sentence case for UI labels and body copy. Use camelCase or PascalCase when naming variables and classes in code. Use snake_case for Python variables, database column names, and file names on Linux. Use kebab-case for CSS classes, HTML IDs, and URL slugs. Use CONSTANT_CASE for environment variables and configuration keys.
