Frequently Asked Questions
What's the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter and capitalizes the first letter of subsequent words (e.g., "myVariableName"), while PascalCase capitalizes the first letter of every word including the first one (e.g., "MyVariableName"). camelCase is commonly used for variable and function names in JavaScript, Java, and C#, while PascalCase is used for class names and components.
When should I use snake_case vs kebab-case?
snake_case (words separated by underscores) is commonly used in Python, Ruby, and database column names (e.g., "user_name"). kebab-case (words separated by hyphens) is used in URLs, CSS class names, and file names (e.g., "my-component.js"). The choice depends on your programming language or context.
How does the tool handle numbers and special characters?
Numbers are preserved in all formats (e.g., "test123" becomes "Test123" in Title Case). For camelCase, PascalCase, snake_case, and kebab-case, special characters (except numbers) are removed, and the text is split into words. For UPPERCASE, lowercase, Title Case, and Sentence case, special characters are preserved.
Can I convert text with mixed separators?
Yes! The tool intelligently detects word boundaries whether your text uses spaces, hyphens, underscores, or camelCase. For example, "hello-world_test" will be correctly converted to "helloWorldTest" (camelCase), "HelloWorldTest" (PascalCase), "hello_world_test" (snake_case), or "hello-world-test" (kebab-case).
