Frequently Asked Questions
What case styles are supported?
Eight styles: camelCase, snake_case, kebab-case, PascalCase, UPPER_SNAKE_CASE (CONSTANT_CASE), dot.case, Title Case, and Sentence case.
How does the word splitting work?
The tool intelligently splits words on spaces, underscores, hyphens, dots, and camelCase boundaries. So "myVariableName", "my_variable_name", and "my-variable-name" all produce the same word list.
Which case style should I use?
It depends on the language and context. JavaScript uses camelCase for variables and PascalCase for classes. Python uses snake_case. CSS uses kebab-case. Constants typically use UPPER_SNAKE_CASE.
Can I convert multiple variable names at once?
Enter each variable name on a separate line and the tool will convert all of them simultaneously. This is useful when refactoring code that switches between naming conventions, such as converting a list of Python snake_case variables to JavaScript camelCase.
