How to use this calculator
- Type or paste your text.

How it works
Converts your text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case and kebab-case.
Worked example
"hello world". → Hello World (title), helloWorld (camel), hello_world (snake).
Common mistakes
- Using title case for headings with small words — most styles keep short articles and prepositions lowercase.
- Running sentence case over text with proper nouns, which then need fixing by hand.
Frequently asked questions
What case styles can it convert to?
Upper, lower, sentence, title, camelCase, snake_case and more — handy for code, headings and tidying pasted text.
Does it work offline?
Yes — it runs in your browser with no server, so it works offline once the page has loaded and never uploads your text.
What's the difference between camelCase, snake_case and kebab-case?
camelCase joins words with capitals (helloWorld), snake_case uses underscores (hello_world), and kebab-case uses hyphens (hello-world). All are common in code and file names.
