- camelCase: No spaces, first word starts with lowercase, subsequent words capitalized.
- PascalCase: Like camelCase but with the first word capitalized too.
- snake_case: All lowercase with underscores between words.
- kebab-case: All lowercase with hyphens between words.
- CONSTANT_CASE: All uppercase with underscores between words.

Frequently Asked Questions
Why would I need to convert text case?
Text case conversion is useful in many scenarios:
- Developers need different case formats for variable naming in different programming languages
- Content writers may need to format titles, headings, or specific text styles
- Data analysts often need to standardize text data before processing
- Designers working on typography and layout may need text in specific formats
- Converting text for legal documents, where specific capitalization may be required
What's the difference between camelCase and PascalCase?
Both camelCase and PascalCase remove spaces and punctuation, with each word joined together and capitalized. The only difference is the first word:
- camelCase: The first word starts with a lowercase letter (e.g., "thisIsCamelCase")
- PascalCase: The first word also starts with an uppercase letter (e.g., "ThisIsPascalCase")
camelCase is commonly used for variable and function names in JavaScript, Java, and other languages, while PascalCase is often used for class names and component names in languages like C# and for React components.
When should I use snake_case versus kebab-case?
Both snake_case and kebab-case are word-separation conventions, but they're used in different contexts:
- snake_case (with underscores) is commonly used in Python, Ruby, and PHP for variable and function names. It's also used for database column names in many systems.
- kebab-case (with hyphens) is mostly used in URLs, HTML attributes, CSS properties, and file names. The hyphen isn't valid in variable names in most programming languages, which is why kebab-case is rarely used for code identifiers.
Tips and Best Practices
- For code variables, match the case style to your programming language's conventions (e.g., camelCase for JavaScript, snake_case for Python)
- In file names, kebab-case is often preferred as it's URL-friendly and works well across operating systems
- For titles and headings, Title Case is typically used in English publications, while Sentence case is common in some European styles
- When converting to camelCase, PascalCase, snake_case, or kebab-case, special characters are removed to ensure the result works in programming contexts
- UPPERCASE is often used for constants in programming or for emphasizing text in documents
