Text Case Converter — All Formats Explained

UPPERCASE converts every letter to capital. Used for headings, acronyms, and emphasis. lowercase converts every letter to small case. Common in URLs and informal writing. Title Case capitalizes the first letter of every word — standard for headings, book titles, and article titles.

camelCase removes spaces and capitalizes each word except the first — widely used in JavaScript variable names. PascalCase is like camelCase but capitalizes the first word too — used in class names. snake_case replaces spaces with underscores — common in Python and database column names. kebab-case uses hyphens — the standard for CSS classes and URL slugs.
