How it works
For identifier styles (camelCase, snake_case, kebab-case…) the tool first splits your text into words — at spaces, underscores, hyphens, dots and between a lower-case and an upper-case letter — so it can convert from any style to any other: helloWorld_foo-bar becomes hello_world_foo_bar in snake case.
Title Case capitalises every word and doesn't skip small words like “of” or “the”, which style guides handle differently. Sentence case capitalises the first letter after each full stop. Accented and non-Latin letters follow the standard Unicode case rules. For counting what you've written see the Word Counter; for encoding see URL Encode and Decode.
Assumptions and limits
- English-style Title Case (no small-word exceptions).
