Case Converter Guide: camelCase, snake_case, kebab-case and More
Master text case conversion for programming — convert between camelCase, PascalCase, snake_case, kebab-case, and other naming conventions used in code.
Why Case Conversion Matters in Programming
Different programming languages and frameworks use different naming conventions. JavaScript uses camelCase for variables, Python uses snake_case, HTML attributes use kebab-case, and C# uses PascalCase for classes. A Case Converter helps you transform text between these formats instantly without manual editing.
camelCase vs PascalCase vs snake_case
camelCase starts with a lowercase letter and capitalizes each subsequent word (e.g., firstName). PascalCase capitalizes every word (e.g., FirstName). snake_case uses underscores between lowercase words (e.g., first_name). kebab-case uses hyphens (e.g., first-name). UPPER CASE converts everything to uppercase, and Title Case capitalizes the first letter of each word.
Common Use Cases for Case Conversion
Developers use case converters when migrating code between languages, renaming API response fields, converting database column names to JavaScript properties, creating CSS class names from component names, and standardizing naming conventions across a codebase.
Programming Language Conventions
JavaScript/TypeScript: camelCase for variables, PascalCase for classes. Python: snake_case for everything. Java: camelCase for methods, PascalCase for classes. Ruby: snake_case. Go: camelCase for exported, PascalCase for unexported. Rust: snake_case. PHP: camelCase for methods, snake_case for functions.
