About this tool
Convert text to any programming naming convention with our free case converter tool. Transform text to camelCase (myVariableName), PascalCase (MyClassName), snake_case (my_variable_name), kebab-case (my-css-class), or CONSTANT_CASE (MY_CONSTANT_VALUE) instantly. Perfect for formatting variable names, function names, class names, file names, CSS classes, API endpoints, database columns, or any code identifier requiring specific naming conventions.
Our converter intelligently handles various input formats: splits on spaces, underscores, hyphens, or case changes, then reconstructs the text in your chosen format. It removes special characters, handles numbers appropriately, and follows programming language conventions. The tool works with single words, phrases, sentences, or existing code identifiers, making it versatile for any conversion scenario.
Essential for developers switching between programming languages with different conventions, refactoring code to match style guides, converting API documentation examples, formatting database schema names, creating consistent CSS class names, preparing variable names from plain text descriptions, and ensuring naming consistency across projects. Saves time and prevents naming errors.
All conversions happen instantly in your browser - your code stays completely private with no server uploads. No registration required, works on all devices, and functions offline. Free to use unlimited times for all your programming needs.
Usage examples
Text to camelCase Variable
Input: "user first name" Output format: camelCase
Output: "userFirstName" (First word lowercase, subsequent words capitalized, no spaces)
Text to PascalCase Class Name
Input: "shopping cart item" Output format: PascalCase
Output: "ShoppingCartItem" (All words capitalized, no spaces - perfect for class names)
Text to snake_case
Input: "Calculate Total Price" Output format: snake_case
Output: "calculate_total_price" (All lowercase, underscores between words - Python/Ruby style)
Text to kebab-case
Input: "Primary Button Style" Output format: kebab-case
Output: "primary-button-style" (All lowercase, hyphens between words - CSS class style)
Text to CONSTANT_CASE
Input: "max retry attempts" Output format: CONSTANT_CASE
Output: "MAX_RETRY_ATTEMPTS" (All uppercase, underscores between words - constant naming)

FAQs
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (myVariableName), while PascalCase starts with an uppercase letter (MyClassName). In programming, camelCase is typically used for variables and functions, while PascalCase is used for class names, types, and components. They're otherwise identical - both capitalize the first letter of each word except camelCase lowercases the first word.
When should I use snake_case vs kebab-case?
snake_case (using underscores) is common in Python, Ruby, and database column names. kebab-case (using hyphens) is standard for CSS classes, HTML IDs, and URLs. Most programming languages don't allow hyphens in variable names, so snake_case is more universal for code. Use kebab-case for web-related naming where hyphens are allowed.
How does the tool handle numbers in text?
Numbers are preserved in their position. "user 1 data" becomes "user1Data" in camelCase, "user_1_data" in snake_case, etc. The tool treats numbers as part of the word they're adjacent to. If you have "2nd attempt", it becomes "2ndAttempt" (camelCase) or "2nd_attempt" (snake_case).
What happens to special characters and punctuation?
Special characters and punctuation are removed since they're not valid in most programming identifiers. "user's name" becomes "usersName" in camelCase. Only letters, numbers, and the format-specific separator (underscore or hyphen) remain in the output.
Can I convert existing code variable names?
Yes! Input can be in any format. If you paste "my_variable_name" (snake_case) and select camelCase, you'll get "myVariableName". The tool detects word boundaries from spaces, underscores, hyphens, or case changes, so it works with any existing naming convention.
What is CONSTANT_CASE used for?
CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) is used for constants - values that never change during program execution. Examples: MAX_USERS, API_KEY, DEFAULT_TIMEOUT. The all-caps format makes constants visually distinct from variables. It's standard in most programming languages for constant naming.
Are there character limits for variable names?
This tool has no character limits, but programming languages do. Most languages allow 255+ characters for identifiers, though extremely long names are bad practice. Keep variable names concise and meaningful. If the tool outputs a very long name, consider abbreviating or simplifying your input text.
Which format should I use for JavaScript?
JavaScript conventions: camelCase for variables and functions (myFunction), PascalCase for classes and constructors (MyClass), CONSTANT_CASE for constants (MAX_SIZE). For file names, many use kebab-case (my-component.js) though camelCase is also common. Follow your project's style guide for consistency.
