About Case Converter

Convert text between every common programming and writing case in one place. Type or paste a string and it is instantly rewritten as UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case — each on its own copy-ready line.

The splitter is identifier-aware, so it correctly breaks apart existing camelCase, snake_case and kebab-case names before recombining them, letting you convert any naming convention straight into another.

What people use it for

Rename a variable from snake_case to camelCase (or the reverse) for a different language's style guide.
Turn a feature title into a PascalCase component name or a kebab-case CSS class.
Generate a CONSTANT_CASE environment-variable name from a plain phrase.
Fix the capitalization of a heading with Title Case or Sentence case.

Frequently asked questions

Which cases are supported?

Ten: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case — all shown at once.

Can it convert camelCase back to words?

Yes. The word splitter recognizes camel/Pascal humps, underscores and hyphens, so it round-trips between any two conventions.

Is it private?

Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
