camelCase joins words together, capitalising each word except the first: 'hello world' becomes 'helloWorld'.

What happens to numbers and acronyms?

Digits stay attached to the word before them and an acronym becomes one word: 'user ID 2' becomes 'userId2' and 'XMLHttpRequest' becomes 'xmlHttpRequest'.

Can it convert from snake_case or kebab-case?

Yes. The tool splits on spaces, underscores, hyphens, and camelCase boundaries before reformatting.

How is camelCase different from PascalCase?

camelCase starts with a lowercase letter and capitalises every subsequent word: helloWorld. PascalCase capitalises the first letter too: HelloWorld. Use camelCase for variables and function names in JavaScript.

How it works

For camelCase, snake_case, kebab-case and PascalCase, the tool tokenises your input by splitting on spaces, underscores, hyphens, other punctuation and camelCase boundaries, then rebuilds the words in the target format. UPPER CASE, lower case and Title Case change letter case in place and keep your line breaks, spacing and punctuation. Everything runs in JavaScript inside your browser tab.

Processing runs in your browser

All conversion happens using the browser's built-in JavaScript engine. Our servers are not involved at any point.
