Frequently asked questions
Which cases can it produce?
Uppercase, lowercase, Title Case, camelCase, snake_case, kebab-case, PascalCase, and CONSTANT_CASE.
Does it handle multi-word input correctly?
Yes. It detects word boundaries from spaces and existing casing, then rejoins the words in the target convention.
Is my text sent anywhere?
No. The transformation runs entirely in your browser, so nothing — including private code — is uploaded.
What input does it take?
Plain text (text/plain), whether typed in or pasted from a file.
Is there a length limit?
No practical limit for typical snippets; processing is local and effectively instant for normal text sizes.
Does it preserve numbers and acronyms?
Numbers pass through as word segments; acronyms follow the chosen case's standard rules for joining words.
