Whether you're writing code, formatting documents, or working with naming conventions, this tool makes it easy to convert text to the format you need instantly.

Understanding Text Case Formats

UPPERCASE

All letters are capitalized. Used for emphasis, acronyms, or specific formatting needs.

Example: "HELLO WORLD" or "THIS IS UPPERCASE"

lowercase

All letters are in lowercase. Used for standard text, filenames, or when case doesn't matter.

Example: "hello world" or "this is lowercase"

Title Case

The first letter of each major word is capitalized. Used for titles, headings, and proper formatting.

Example: "Hello World" or "This Is Title Case"

Sentence case

Only the first letter of the first word is capitalized. Used for standard sentences.

Example: "Hello world" or "This is sentence case"

camelCase

The first word is lowercase, and subsequent words start with uppercase. No spaces. Used in programming for variable names, function names, and identifiers.

Example: "helloWorld" or "thisIsCamelCase"

PascalCase

The first letter of each word is capitalized. No spaces. Used in programming for class names, constructors, and type names.

Example: "HelloWorld" or "ThisIsPascalCase"

snake_case

All words are lowercase, separated by underscores. Used in programming for variable names, especially in Python and other languages.

Example: "hello_world" or "this_is_snake_case"

kebab-case

All words are lowercase, separated by hyphens. Used in URLs, CSS class names, and HTML attributes.

Example: "hello-world" or "this-is-kebab-case"

Programming Naming Conventions

JavaScript

Variables and Functions: camelCase (e.g., myVariable, calculateTotal)
Classes: PascalCase (e.g., UserAccount, DatabaseConnection)
Constants: UPPERCASE (e.g., MAX_SIZE, API_KEY)

Python

Variables and Functions: snake_case (e.g., my_variable, calculate_total)
Classes: PascalCase (e.g., UserAccount, DatabaseConnection)
Constants: UPPERCASE (e.g., MAX_SIZE, API_KEY)

CSS and HTML

Class Names: kebab-case (e.g., main-container, button-primary)
IDs: kebab-case (e.g., header-nav, footer-content)

Tips and Best Practices

💡 Pro Tip: When converting programming identifiers, be careful with abbreviations and acronyms. Some conventions treat them differently (e.g., XMLHttpRequest vs xmlHttpRequest).

Consistency

Choose a naming convention and stick to it within a project
Follow language-specific conventions when programming
Maintain consistency across related files or codebases

Readability

Use descriptive names that clearly indicate purpose
Avoid overly long names, but prioritize clarity
Use case conversion to improve readability

Frequently Asked Questions

Which case format should I use for programming?

It depends on your programming language and project conventions. JavaScript commonly uses camelCase for variables and PascalCase for classes. Python uses snake_case for variables. CSS uses kebab-case for class names. Follow your language's conventions!

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., MyVariable). camelCase is typically used for variables/functions, while PascalCase is used for classes/types.

Can I convert multiple formats at once?

The tool converts to one format at a time. Simply select different formats to see all variations of your text!

Does the converter preserve special characters?

Yes! The converter preserves numbers, punctuation, and special characters, only changing letter cases as needed for the selected format.

Is the conversion accurate for all languages?

The converter works best with English text using the Latin alphabet. Some special characters and non-Latin scripts may not convert as expected.
