Common Text Case Conventions Explained

• UPPERCASE: Converts every letter into capital letters (e.g., "HELLO WORLD"). Useful for acronyms, legal notices, and high-impact headlines.
• lowercase: Converts all characters to small letters (e.g., "hello world"). Essential for normalizing email addresses, database keys, and file paths.
• Title Case: Capitalizes the initial letter of every major word while keeping minor prepositions lowercase (e.g., "The Art of Web Design"). Standard formatting for article headlines and book titles.
• Sentence case: Capitalizes only the first character of each sentence following punctuation (e.g., "This is a sentence. And another one."). Ideal for standard prose and email drafting.
• camelCase & PascalCase: Formats multi-word strings without spaces for software programming. camelCase starts with a lowercase letter (e.g., userAccountBalance), whereas PascalCase capitalizes the first letter (e.g., UserProfileHeader).
• kebab-case: Replaces spaces and punctuation with hyphens (e.g., text-case-converter). Perfect for SEO-friendly URL slugs and CSS class names.
