What is a case converter?

A case converter is a tool that transforms text between different capitalization formats such as Sentence case, Title Case, UPPER CASE, lowercase, camelCase, PascalCase, snake_case, and kebab-case. It is used by writers, developers, SEO professionals, and students to quickly reformat text.

What is Sentence Case?

Sentence case capitalizes only the first letter of the first word in a sentence (and proper nouns) while keeping the rest lowercase. Example: "the quick brown fox" → "The quick brown fox". It follows standard grammatical rules for professional writing.

Title Case capitalizes the first letter of most words in a title while keeping short prepositions, conjunctions, and articles lowercase (e.g., "of", "and", "the"). Example: "the art of war" → "The Art of War". Different style guides (APA, Chicago, MLA) have slightly different rules.

camelCase writes compound words with no spaces, where each word after the first starts with a capital letter. Example: "user profile settings" → "userProfileSettings". It is widely used in JavaScript, Java, and TypeScript for variable and function names.

snake_case writes compound words in all lowercase separated by underscores. Example: "user profile settings" → "user_profile_settings". It is the standard naming convention in Python, Ruby, and SQL databases.

kebab-case (also called dash-case or hyphen-case) writes compound words in all lowercase separated by hyphens. Example: "user profile settings" → "user-profile-settings". It is used in CSS class names, URL slugs, and HTML attributes.

What is UPPER CASE?

UPPER CASE (also called ALL CAPS) means every letter in the text is a capital letter. Numbers and special characters remain unchanged. It is created by applying the toUpperCase() function to each character.

UPPER CASE text is used for emphasis, acronyms, headings, warnings, and design elements where visual impact matters.
