FAQ

Common questions

What is Title Case vs Sentence case?

Title Case capitalizes the first letter of every major word (e.g. The Quick Brown Fox), while Sentence case only capitalizes the first word of each sentence.

What programming cases are supported?

We support camelCase, PascalCase, kebab-case (URL friendly), snake_case (Python/SQL friendly), and CONSTANT_CASE (environment variables).

Does converting case strip punctuation?

Standard cases preserve all punctuation; code identifier cases (like snake_case and kebab-case) normalize punctuation into clean delimiters.
