FAQ
What is camelCase vs snake_case?
camelCase combines words without spaces, capitalizing each word after the first (helloWorld). snake_case uses underscores between words (hello_world). Both are common in programming.
Does my text leave the browser during conversion?
No. Case transformations use JavaScript's built-in toUpperCase(), toLowerCase(), and custom logic — all running client-side. Your text remains in browser memory throughout.
Does Title Case capitalize small words?
Our Title Case capitalizes the first letter of each word. For APA/MLA style (lowercase for articles, conjunctions), you may need to adjust manually.
