These are the four most common programming case styles. camelCase starts lowercase with capital letters for each new word (myVariableName). PascalCase capitalizes every word including the first (MyClassName). snake_case uses underscores between lowercase words (my_variable_name). kebab-case uses hyphens between lowercase words (my-css-class).

Title Case capitalizes the first letter of every major word (The Quick Brown Fox), while minor words like "a," "the," "and," and "of" remain lowercase unless they're the first or last word. Sentence case capitalizes only the first word and proper nouns (The quick brown fox). Title case is used for headlines and book titles, while sentence case is common in blog posts, emails, and modern UI design.

JavaScript uses camelCase for variables and functions (e.g., myVariable, getUserData), PascalCase for classes and constructors (e.g., UserProfile, HttpClient), and CONSTANT_CASE for constants (e.g., MAX_RETRIES, API_URL). Following these conventions improves code readability and aligns with community standards.

Use kebab-case for URLs, CSS class names, HTML attributes, and file names (e.g., my-component.html, user-profile-card). Use snake_case for Python code, database table names, column names, and configuration files. Kebab-case works well for web contexts because underscores can be problematic in URLs, while snake_case is preferred in databases and Python.

Python uses snake_case for functions and variables (e.g., get_user_data, total_count), PascalCase for class names, and SCREAMING_SNAKE_CASE for constants. JavaScript uses camelCase for functions and variables, PascalCase for classes, and CONSTANT_CASE for constants. These conventions are outlined in PEP 8 for Python and the Airbnb Style Guide for JavaScript.

CSS classes should use kebab-case (e.g., btn-primary, user-profile-card), REST API endpoints should use kebab-case for URLs (e.g., /api/user-profile), and database columns should use snake_case (e.g., user_id, created_at). These conventions are widely accepted industry standards that improve code readability and maintainability.

SCREAMING_SNAKE_CASE (also called CONSTANT_CASE) is used for constants and environment variables in most programming languages. The uppercase letters make constants visually distinct from regular variables, signaling that these values should not be changed during runtime.

PascalCase and UpperCamelCase are the same thing - just different names for the same convention. Both refer to capitalizing the first letter of every word with no separators, like UserProfile or HttpRequest. The term PascalCase comes from the Pascal programming language where this style was standard.

Yes! You can upload text files or paste multiple lines of text, and the tool will convert each line individually. This is perfect for batch converting variable names, CSS classes, or database column names. Each line is treated as a separate identifier and converted according to the selected case style.

Most programming languages have libraries for case conversion. In JavaScript, use libraries like lodash (_.camelCase, _.snakeCase, _.kebabCase) or change-case. In Python, use the inflection library or write simple string methods. For bulk refactoring in code editors, use find-and-replace with regex or dedicated refactoring tools.

This tool processes text entirely in your browser with no practical character limit - you can convert files with thousands of lines. The tool handles Unicode characters, numbers, and special symbols. Non-alphanumeric characters are removed or converted to separators depending on the target case style.
