Frequently Asked Questions
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter and capitalizes subsequent words (like myVariableName), commonly used for JavaScript variables and functions. PascalCase capitalizes every word including the first (like MyClassName), typically used for class names and components in many programming languages.
When should I use snake_case vs kebab-case?
snake_case (words_separated_by_underscores) is commonly used in Python, Ruby, and database field names. kebab-case (words-separated-by-hyphens) is preferred for URLs, CSS class names, and file names because hyphens are URL-safe and more readable in web contexts.
What are the rules for Title Case?
Title Case capitalizes the first and last words, plus all major words in between. Articles (a, an, the), conjunctions (and, but, or), and short prepositions (in, on, at) are typically lowercase unless they're the first or last word. Our converter follows these standard rules automatically.
What is Sentence case?
Sentence case capitalizes only the first letter of the first word (and proper nouns), treating the text like a standard sentence. It's natural for body text and less formal than Title Case. For example: 'This is sentence case formatting.'
What is CONSTANT_CASE or SCREAMING_SNAKE_CASE?
CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) uses ALL UPPERCASE letters with underscores separating words. It's traditionally used for constants in programming languages like C, Java, and Python to indicate values that shouldn't change. Example: MAX_FILE_SIZE or API_KEY.
Can this tool handle special characters and numbers?
Yes! The converter intelligently handles special characters, numbers, and punctuation. Numbers are preserved in their position, special characters are handled according to the selected case style (removed, converted to separators, or preserved).
Will this tool work with non-English text?
Yes, the converter works with Unicode characters and supports accented letters and characters from many languages. Uppercase and lowercase conversions respect language-specific capitalization rules where supported by the browser.
Can I convert entire documents or just small snippets?
Both! There's no practical character limit. Convert single words, sentences, paragraphs, or entire documents. The tool handles everything from variable names to full articles efficiently.
