Frequently Asked Questions

What's the difference between title case and sentence case?

Title Case Capitalizes First Letter Of Every Word. Sentence case capitalizes only the first letter of the sentence. Title case for headers/titles. Sentence case for normal paragraphs.

When should I use camelCase vs snake_case?

camelCase: JavaScript, Java variables (firstName, getUserData). snake_case: Python, Ruby, SQL (first_name, get_user_data). SCREAMING_SNAKE_CASE: Constants (MAX_RETRIES). Follow language conventions.

Does this preserve special characters and numbers?

Yes. Special characters (!@#$%^&*) and numbers (0-9) remain unchanged. Only letter casing converts. Useful for converting text with mixed alphanumeric content.
