Questions
What is the difference between camelCase and PascalCase?
In camelCase the first word is lowercase and subsequent words are capitalized (e.g., myVariableName), while PascalCase capitalizes every word including the first (e.g., MyVariableName). camelCase is common for variables and PascalCase for class names.
How do I convert snake_case to camelCase?
Paste your snake_case text into the input field and select camelCase as the output format. The tool splits on underscores and capitalizes each subsequent word automatically.
What string cases does this converter support?
Supported cases include camelCase, PascalCase, snake_case, kebab-case, UPPER_SNAKE_CASE, Title Case, lowercase, and UPPERCASE.
Can I convert multiple variable names at once?
Yes, paste multiple names separated by newlines and each one will be converted independently to your chosen case format.
Does the string case converter work offline?
Yes, all conversions run in your browser using client-side JavaScript. No data is sent to a server, and the tool works without an internet connection after the page loads.
