Convert text, code identifiers, database columns, and titles between camelCase, snake_case, kebab-case, Title Case, PascalCase, CONSTANT_CASE, and more. 100% private in your browser.
Consistent naming conventions are foundational for maintainable software architecture. Mixing different case styles within a single module increases cognitive load, complicates automated code linters, and introduces subtle bugs during JSON serialization and API payload exchanges.
For instance, converting a backend Python or Laravel snake_case database schema into frontend TypeScript camelCase interfaces is a daily task for full-stack developers. Case Converter Studio automates this conversion in bulk across hundreds of columns in milliseconds.
Unlike simplistic converters that blindly capitalize the initial letter of every single word, our algorithm integrates the Chicago Manual of Style and AP Stylebook rules.
Common prepositions, articles, and conjunctions (the, and, of, with, in) stay lowercase unless they occupy the first or final position of a heading, ensuring professional headlines for blogs and newsletters.

| Case Style | Delimiter / Rule | Example Output | Primary Ecosystems & Use Cases |
|---|---|---|---|
| camelCase | Initial lowercase, subsequent capitalized | userFirstName | JavaScript, TypeScript, Java variables, JSON keys |
| PascalCase | Every word capitalized, no delimiter | UserFirstName | React components, C#, Go structs, Python classes |
| snake_case | All lowercase, separated by underscore | user_first_name | Python, Ruby, Rust, SQL columns, PostgreSQL |
| kebab-case | All lowercase, separated by hyphen | user-first-name | CSS classes, HTML attributes, URL slugs, Vue props |
| CONSTANT_CASE | All uppercase, separated by underscore | USER_FIRST_NAME | Environment variables (.env), constants, Enum values |
| Title Case | Major words capitalized with spaces | User First Name | Article headlines, book titles, button text, UI headers |
| Sentence case | First word of sentence capitalized | User first name | Modern UI copywriting, microcopy, error messages |
| dot.case | All lowercase, separated by period | user.first.name | Java package paths, translation keys (i18n), loggers |
| Header-Case | Capitalized words separated by hyphen | User-First-Name | HTTP headers (e.g. Content-Type, X-Request-Id) |
userFirstName). It is the standard convention for variables and function names in JavaScript, TypeScript, and Java. PascalCase (also known as UpperCamelCase) capitalizes every word including the first (such as UserFirstName), and is the standard convention for classes, interfaces, and React/Vue components.
user_first_name). It is standard for database tables, SQL columns, and variables in Python and Rust. CONSTANT_CASE (also referred to as SCREAMING_SNAKE_CASE) uses all uppercase letters joined by underscores (e.g. DATABASE_HOST_PORT) and is reserved for application configurations, environment variables (.env), and immutable constants.
