About case conversion
In programming, how variables and functions are named (naming conventions) varies by language and team. This tool converts the words you enter into various notations at once. It recognizes spaces, underscores, hyphens, and capital-letter boundaries as word separators.
Supported notations
- camelCase: first letter lowercase, later words capitalized (e.g.
getUserName) - PascalCase: each word capitalized (e.g.
GetUserName) - snake_case: lowercase with underscores (e.g.
get_user_name) - kebab-case: lowercase with hyphens (e.g.
get-user-name) - CONSTANT_CASE: uppercase with underscores (e.g.
GET_USER_NAME)
All conversion happens in your browser, and your input is never sent anywhere.
FAQ
Can it convert multiple words or phrases?
Yes. It recognizes spaces, symbols, and capital-letter boundaries as word separators and converts accordingly.
Can it convert Japanese?
Japanese has no concept of case (upper/lower), so it's left as-is. Use it for converting alphanumeric names.
Can I copy the results?
The copy button to the right of each notation copies the result in that format.
Is my data sent anywhere?
