About this tool
Different contexts call for different capitalization: a heading wants Title Case, a variable name wants camelCase or snake_case, a constant wants CONSTANT_CASE. Retyping text by hand to match is tedious and error-prone. This tool converts your text into nine common case styles instantly.
Frequently asked questions
- How does Title Case handle small words like "the" or "of"?
- It lowercases common short words (articles, conjunctions, short prepositions) in the middle of a title, while always capitalizing the first and last word, matching typical title-casing conventions.
- What counts as a "word" for camelCase or snake_case?
- Runs of letters and numbers are treated as words, and everything else (spaces, punctuation, existing hyphens or underscores) is treated as a separator. So "hello-world 123" becomes "helloWorld123" in camelCase.
