What does it do?
It converts identifiers and text between the naming conventions used in code: camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, Title Case, Sentence case, dot.case, path/case and Train-Case. Words are detected from any style, so you can paste a mix.
Typical uses
- Map database columns (
created_at) to TypeScript properties (createdAt).
- Turn a component name into a file name (
UserProfileCard → user-profile-card).
- Build environment variable names (
apiBaseUrl → API_BASE_URL).
Example
| Input | camelCase | snake_case | kebab-case |
|---|
| user first name | userFirstName | user_first_name | user-first-name |
| XMLHttpRequest | xmlHttpRequest | xml_http_request | xml-http-request |
Perguntas frequentes
›How are acronyms like HTTP or XML handled?
They are kept as one word: XMLHttpRequest becomes xml_http_request and getHTTPResponseCode becomes get-http-response-code. Numbers stay attached to the word before them.
›Can I convert many names at once?
Yes. Paste one identifier per line, for example the columns of a table or the keys of an API response, and every style shows the whole list converted.
›Which style should I use?
It depends on the ecosystem: camelCase for JavaScript variables and JSON from JS APIs, PascalCase for classes and React components, snake_case for Python and SQL columns, kebab-case for URLs, CSS classes and file names, and CONSTANT_CASE for constants and environment variables.
