Main Features & Case Types
lowercase (Lowercase)
Converts all characters to lowercase. This is the simplest conversion.
- Usage: URL normalization, email addresses, data processing
- Example: "Hello World" → "hello world"
UPPERCASE (Uppercase)
Converts all characters to uppercase. Perfect for headings and emphasis.
- Usage: Headings, acronyms, important texts
- Example: "Hello World" → "HELLO WORLD"
Title Case (Title Formatting)
Capitalizes the first letter of each word. The ideal formatting for titles and headings.
- Usage: Book titles, article headings, product names
- Example: "the quick brown fox" → "The Quick Brown Fox"
Sentence case (Sentence Beginning)
Only the first letter of a sentence is capitalized. All other words remain lowercase.
- Usage: Normal sentences, flowing text in documents
- Example: "HELLO WORLD how are you" → "Hello world how are you"
ℹ️ Info: Sentence Case respects line breaks and starts each new
sentence with a capital letter after punctuation marks (., !, ?).
camelCase (Camel Case)
The first word starts lowercase, each following word begins with uppercase. No separators
between words. This is the standard naming convention in JavaScript and Java.
- Usage: JavaScript/Java variable names, DOM properties
- Example: "hello world" → "helloWorld"
Note: camelCase automatically removes special characters and spaces!
PascalCase (Pascal Case)
Like camelCase, but the first word also starts with uppercase. This is the standard for
class names and component names.
- Usage: JavaScript class names, React/Angular component names
- Example: "hello world" → "HelloWorld"
Practical Example: Component naming
Input: "user profile component" → Output: "UserProfileComponent"
kebab-case (Kebab Case)
Words are separated by hyphens and lowercase. This is the standard for CSS class names and
URLs.
- Usage: CSS class names, URL slugs, HTML attributes
- Example: "hello world" → "hello-world"
Note: kebab-case automatically removes special characters and replaces
them with hyphens!
snake_case (Snake Case)
Words are separated by underscores and lowercase. This is the standard in Python and
databases.
- Usage: Python variable names, database columns, SQL queries
- Example: "hello world" → "hello_world"
Practical Example: Database column
Input: "user first name" → Output: "user_first_name"

Practical Examples
Backend API Development
Task: Create API endpoints with consistent naming
Input: "get user profile" → camelCase: "getUserProfile" → kebab-case: "get-user-profile"
Usage: JavaScript function is called "getUserProfile", the REST endpoint is
"/get-user-profile"
Database Design
Task: Consistent column naming in the database
Input: "User First Name" → snake_case: "user_first_name"
All database field names follow the snake_case convention for better compatibility
URL Slug Generation
Task: Structure blog articles SEO-friendly
Input: "The Best JavaScript Tips 2024" → kebab-case: "the-best-javascript-tips-2024"
The URL becomes: www.myblog.com/articles/the-best-javascript-tips-2024 – perfect for
SEO!
