Case Converter

Convert text between camelCase, snake_case, kebab-case, PascalCase, CONSTANT_CASE, Title Case and more — instantly in your browser.

This case converter switches text between camelCase, snake_case, kebab-case, PascalCase, CONSTANT_CASE, Title Case and more, all at once. Use it to rename an identifier, convert a variable to snake_case, or turn a phrase into a slug-style kebab-case. It detects word boundaries from spaces, hyphens, underscores and capital letters, so mixed names split correctly. It runs in your browser.

Every common case, computed at once.

camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, dot.case, Title Case, Sentence case, UPPERCASE and lowercase.
How does it split words?
