Title Case: Capitalizes the first letter of each word. Standard for book titles, article headlines, and formal document titles following English capitalization rules.

Sentence case: Capitalizes only the first letter of the first word and proper nouns. Natural for standard writing, descriptions, and body text.

Programming Case Formats

camelCase: First word lowercase, subsequent words capitalized with no spaces. Common in JavaScript, Java, and TypeScript for variable and function names.

PascalCase: Every word capitalized with no spaces. Standard for class names in most programming languages including C#, Java, and TypeScript.

snake_case: All lowercase with underscores separating words. Preferred in Python, Ruby, and database naming conventions.

kebab-case: All lowercase with hyphens separating words. Common in URLs, CSS class names, and file names.

CONSTANT_CASE: All uppercase with underscores. Standard for constants and environment variables in most programming languages.

Common Use Cases

Developers use case converters to quickly transform text between naming conventions when refactoring code, migrating between languages with different standards, or ensuring consistency across codebases. Content writers apply title case to headlines, adjust emphasis with uppercase, and normalize formatting in bulk text.

Data professionals clean inconsistent datasets by normalizing case formatting. Social media managers adjust text case for platform-specific aesthetic requirements. Students and academics format titles and citations according to style guide requirements.
