Frequently Asked Questions

In camelCase, the first word starts with a lowercase letter and each subsequent word starts with an uppercase letter (e.g., myVariableName). In PascalCase, every word including the first starts with an uppercase letter (e.g., MyVariableName).
Title Case capitalizes the first letter of each major word while keeping minor words like "a," "an," "the," "and," "but," "or," "in," "on," and "at" in lowercase - unless they appear at the start of the text.
CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) is commonly used for constant values in programming. All letters are uppercased and words are separated by underscores, such as MAX_RETRY_COUNT.
Yes. Numbers and special characters are preserved during conversion. The tool focuses on changing letter casing while leaving non-alphabetic characters intact in most modes. For code-style cases like camelCase and snake_case, spaces and punctuation are replaced with the appropriate separator.
Kebab-case uses lowercase letters with words separated by hyphens (e.g., my-component-name). It is widely used in URLs, CSS class names, HTML attributes, and file names in web development projects.
