About the Case Converter

A case converter changes the capitalization of your text without you retyping it. It is handy for fixing text typed with caps lock on, formatting headings in Title Case, or turning labels into programmer-friendly camelCase, snake_case or kebab-case.

Everything is processed in your browser — paste sensitive text with confidence, because nothing is transmitted anywhere. The camelCase, snake_case and kebab-case options intelligently split on spaces, hyphens and underscores so mixed input still converts cleanly.

Frequently asked questions

What is Sentence case?

Sentence case capitalizes only the first letter of each sentence, like normal prose.

What is the difference between snake_case and kebab-case?

snake_case joins words with underscores (my_variable); kebab-case joins them with hyphens (my-variable).
