About Case Converter

A case converter transforms text between naming and writing styles. Paste text and switch instantly between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, and kebab-case — the splitter even breaks camelCase input apart correctly. It runs in your browser with no upload.

Frequently asked questions

What's the difference between camelCase and snake_case?
camelCase joins words and capitalizes each after the first (myVariableName); snake_case lowercases words and joins them with underscores (my_variable_name).
Will it split camelCase input correctly?
Yes. It inserts word boundaries at lower-to-upper transitions, so 'fooBarBaz' converts cleanly to snake_case or kebab-case.
Is there a limit on text length?
No practical limit — it converts as much text as your browser can hold, all locally.
