About the Case converter
Title Case here follows common headline style: small words like “a”, “of” and “the” stay lowercase unless they start the title. Style guides differ slightly, so review headlines before publishing.
The programming cases (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE) split on spaces, punctuation and existing capital letters, so “userProfile id” becomes user_profile_id.

Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the main words of a headline. Sentence case only capitalises the first word and proper nouns, like a normal sentence.
Which case should I use for URLs?
kebab-case (lowercase with hyphens). Use the slug generator for a fully cleaned URL slug.
Will it change my proper nouns?
Lowercase and sentence case will lowercase names like “London”. Re-capitalise those after converting.
