All the case styles

Every style is shown together, so you copy the one you need instead of clicking through options. The text-style cases keep your punctuation; the programming cases split on spaces, punctuation and existing capitals, so "userID count" becomes user_id_count.

Title case rules (AP and Chicago)

Title Case capitalises every word except short articles, conjunctions and prepositions (a, an, the, and, but, or, for, of, on, in, to, by, at, as, via) in the middle of a title. The first and last words are always capitalised, as both AP and Chicago style require.

camelCase vs snake_case vs kebab-case

camelCase (userName) is the convention for variables in JavaScript, Java and Swift; PascalCase (UserName) for classes and React components; snake_case (user_name) in Python, Ruby and SQL; kebab-case (user-name) in URLs and CSS class names; CONSTANT_CASE for constants and environment variables.

Programming naming conventions

When converting identifiers, numbers stay attached to the word before them and existing camelCase is split at its capitals, so the result reads the way a developer would write it.
