Variable and Function Naming
When writing code in different languages, quickly check how variable or function names should be formatted. JavaScript prefers camelCase, Python uses snake_case, and constants typically use CONSTANT_CASE.
Inspect text across classic naming conventions in one view.

Whether you're refactoring code, naming variables, or working across different programming languages and frameworks, Case Lab helps you quickly see how text looks in various case formats.
Use Cases
API Endpoint Design
Convert resource names to kebab-case for RESTful API URLs or camelCase for JSON response keys to maintain consistency across your API design.
Database Schema Design
Convert table names and column names to snake_case which is the standard convention in most SQL databases like PostgreSQL and MySQL.
URL Slug Generation
Generate URL-friendly slugs for blog posts, product pages, or any web content by converting titles to lowercase with hyphens.

Frequently Asked Questions
What's the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (e.g., "myVariable"), while PascalCase starts with an uppercase letter (e.g., "MyClass"). PascalCase is typically used for class names, while camelCase is used for variables and functions in languages like JavaScript and Java.
When should I use snake_case vs kebab-case?
snake_case (with underscores) is commonly used in Python, Ruby, and SQL for variable and function names. kebab-case (with hyphens) is typically used in URLs, CSS class names, and file names because hyphens are URL-safe and improve readability.
Can I convert text that's already in a specific case?
Yes! Case Lab can handle input in any format. It intelligently parses the input whether it's already in camelCase, snake_case, or plain text with spaces, and converts it to all other formats.
What is CONSTANT_CASE used for?
CONSTANT_CASE (all uppercase with underscores) is the standard convention for naming constants and environment variables in most programming languages. For example: MAX_RETRY_COUNT, API_KEY, DATABASE_URL.
