About Case Converter
Naming conventions differ by language and by context: constants in SCREAMING_SNAKE_CASE, CSS classes in kebab-case, JavaScript variables in camelCase, headings in Title Case. Retyping between them wastes time and invites typos.
This converter detects word boundaries in whatever you paste - including existing camel case - and rewrites it in nine different conventions, all updating live as you type.
Frequently asked questions
Which words stay lowercase in title case?
Short articles, conjunctions and prepositions are kept lowercase unless they start or end the title, following common style guides.
What is sentence case?
Only the first letter of each sentence is capitalised, along with any word you already wrote in capitals such as an acronym.
Does camelCase handle existing separators?
Yes. Spaces, hyphens, underscores and existing case boundaries are all treated as word breaks.
