Frequently Asked Questions
What text case types are supported?
This tool supports eight conversions: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, kebab-case, and aLtErNaTiNg case.
What is camelCase and when should I use it?
camelCase joins words together with no separators, capitalizing the first letter of each word except the first. It is standard in JavaScript, TypeScript, Java, and C#.
What is the difference between snake_case and kebab-case?
snake_case separates words with underscores and is standard in Python and Ruby. kebab-case separates words with hyphens and is common in CSS class names and URL slugs.
Can I convert text for programming variable names?
Yes. The camelCase, snake_case, and kebab-case outputs are specifically designed for developers.
