Convert text between different letter cases and naming conventions. Perfect for developers, writers, and content creators.
Last updated: March 2026 | By Patchworkr Team
Text case conventions are standardized ways of capitalizing and formatting text. Different programming languages, writing styles, and documentation systems use specific case conventions for consistency and readability.
In programming, naming conventions help developers quickly identify the type and purpose of variables, functions, and classes. For example, camelCase is common in JavaScript for variables, while PascalCase is used for class names. snake_case is prevalent in Python, and CONSTANT_CASE indicates unchangeable values across many languages.
In writing and content creation, Title Case is used for headings, Sentence case for regular text, and UPPERCASE for emphasis or acronyms. Understanding these conventions ensures your code follows best practices and your content maintains professional formatting.
Capitalizes the first letter of each major word. Used for titles, headings, and proper names.
All letters capitalized. Used for acronyms, emphasis, and constants in some languages.
All letters in lowercase. Common for URLs, file names, and certain programming contexts.
Only the first letter capitalized. Standard for regular sentences and paragraphs.
First word lowercase, subsequent words capitalized. Used for JavaScript/Java variables and functions.
Every word capitalized, no spaces. Used for class names in most programming languages.
Words separated by underscores, all lowercase. Common in Python, Ruby, and databases.
Words separated by hyphens, all lowercase. Used for URLs, CSS classes, and file names.
Uppercase with underscores. Used for constants and environment variables in many languages.
Converting a descriptive phrase to proper JavaScript naming:
"user login status"userLoginStatusconst userLoginStatus = true;Converting to Python's preferred naming convention:
"Calculate Total Price"calculate_total_pricedef calculate_total_price():Creating SEO-friendly URLs:
"How To Build A Website"how-to-build-a-websiteexample.com/blog/how-to-build-a-websiteUse camelCase for variables and functions (myVariable, getUserData), PascalCase for classes and components (MyComponent, UserModel), and CONSTANT_CASE for constants (MAX_SIZE, API_KEY).
camelCase starts with a lowercase letter (myVariable), while PascalCase starts with an uppercase letter (MyClass). PascalCase is also called UpperCamelCase.
Python's style guide (PEP 8) recommends snake_case for functions and variables for readability. It's easier to read than camelCase, especially in longer names: calculate_user_total_score vs calculateUserTotalScore.
Yes. Search engines like Google treat hyphens as word separators, making 'best-practices' readable as two words. Underscores are not treated as separators, so 'best_practices' reads as one word.
Technically yes, but it's bad practice. Consistent naming conventions make code more readable and maintainable. Follow your language's or team's style guide for consistency.
In camelCase/PascalCase, treat acronyms as single words: userHtmlParser (not userHTMLParser) or XmlHttpRequest (not XMLHTTPRequest). However, for constants, use all caps: MAX_HTTP_RETRIES.
Yes, most SQL style guides recommend snake_case for table and column names (user_id, created_at) because SQL is case-insensitive and hyphens are not allowed, making snake_case the most readable option.
Numbers are typically preserved: 'user 2 profile' becomes userProfile2 (camelCase) or user_profile_2 (snake_case). Leading numbers are invalid in most programming languages, so avoid them in identifiers.
