Frequently Asked Questions
Title Case capitalizes the first letter of every major word (e.g., "The Quick Brown Fox"). Sentence case only capitalizes the first letter of the first word in a sentence, like standard prose. Title Case is used for headlines; Sentence case for body text.
Yes! Paste as much text as you need — the converter handles large blocks, multiple paragraphs, and line breaks. All structure is preserved; only the letter case changes.
camelCase (helloWorld) is the standard for JavaScript variables and JSON keys. snake_case (hello_world) is preferred in Python and database column names. PascalCase (HelloWorld) is used for class names in most OOP languages. kebab-case (hello-world) is standard for CSS properties and URL slugs.
