FAQ
What case formats are supported?
UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, and more.
Can I convert multiple lines at once?
Yes. Paste multi-line text and each line will be converted independently. Great for batch-converting lists of variable names or headings.
Is this useful for programming?
Absolutely. Developers frequently need to convert between camelCase (JavaScript), snake_case (Python/Ruby), kebab-case (CSS/URLs), and PascalCase (C#/TypeScript classes).
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter and capitalizes the first letter of subsequent words (e.g., myVariableName). PascalCase capitalizes the first letter of every word (e.g., MyClassName).
When should I use CONSTANT_CASE?
CONSTANT_CASE is commonly used for defining constants in programming. Examples include MAX_VALUE, API_BASE_URL, etc. It indicates values that should not be changed.
