How it works

Camel and acronym boundaries are separated, underscore, hyphen, dot, slash, and backslash runs become spaces, and whitespace forms tokens for nine naming styles. Full uppercase and lowercase instead apply directly to the original string.

  • All outputs appear together because languages and configuration formats choose different naming conventions.
  • Title case capitalizes every detected token mechanically and is not a publishing style-guide algorithm.

Worked example

Variable Name
Convert a phrase into various programming naming conventions
Input
											user profile settings
Output
												Camel case: userProfileSettings
Pascal case: UserProfileSettings
Snake case: user_profile_settings
Kebab case: user-profile-settings
Upper case: USER PROFILE SETTINGS
Lower case: user profile settings
Title case: User Profile Settings
Sentence case: User profile settings
Constant case: USER_PROFILE_SETTINGS
Dot case: user.profile.settings
Path case: user/profile/settings

When to use this

JavaScript variables use camelCase, class names use PascalCase, CSS and routes use kebab-case, and environment constants use UPPER_SNAKE_CASE.

Edge cases

  • XMLParser splits at the acronym boundary into XML and Parser before recasing.
  • Punctuation outside the recognized delimiter list remains attached to its token.
  • German ß can uppercase to SS, so Unicode casing may change the output length.
