What Are Common Letter Cases and When Should You Use Them?

| Title Case | The Quick Brown Fox |
Blog titles, book chapters, YouTube video headlines |
| camelCase | userAccountBalance |
JavaScript, Java, Swift variables and functions |
| PascalCase | UserAccountBalance |
C#, TypeScript classes, React components |
| snake_case | user_account_balance |
Python variables, SQL column names, PostgreSQL tables |
| kebab-case | user-account-balance |
SEO URLs, CSS class selectors, HTML attributes |
| CONSTANT_CASE | MAX_UPLOAD_LIMIT |
Environment variables, global configuration constants |

Frequently Asked Questions
- How does Title Case conversion handle minor words?
- Our Title Case algorithm follows Chicago Manual of Style guidelines: it capitalizes the first word and all major nouns, verbs, adjectives, and adverbs while keeping minor conjunctions, prepositions, and articles (such as a, an, the, and, but, or, in, on, of, for) in lowercase unless they appear at the beginning of a title.
- Is my text uploaded or stored on any server?
- No. All text conversions and cleaning operations are executed 100% locally in your web browser using client-side JavaScript. Your text never leaves your device, and no logs or cookies track your inputs.
- What is the difference between camelCase and PascalCase?
- In camelCase, the very first word begins with a lowercase letter and subsequent compound words start with an uppercase letter (e.g., 'getUserProfile'). In PascalCase, every word including the first begins with an uppercase letter (e.g., 'GetUserProfile').
- Can this tool extract links and email addresses from raw text?
- Yes. Click 'Extract Emails' to pull out all valid email addresses into a clean newline-delimited list, or click 'Extract URLs' to isolate all web links from mixed paragraphs and log outputs.
