Frequently Asked Questions
How does Title Case handle small words?
It adheres to standard English typography guidelines, keeping minor conjunctions, prepositions, and articles (e.g., and, of, the, in) lowercase unless they are the first word.
What is a URL-friendly slug?
A slug strips accents and diacritics, converts text to lowercase, and replaces non-alphanumeric characters with hyphens for clean web URLs and file names.
Can it convert code identifiers like camelCase to snake_case?
Yes! The converter automatically identifies word boundaries within camelCase and PascalCase strings.
