Text Case Converter

Convert text between different case formats.

Text Case Conversion

Convert text between different case formats: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, and more. Essential for standardizing data or converting between naming conventions.

Programmers constantly switch between camelCase (JavaScript), snake_case (Python/Ruby), PascalCase (C#), and kebab-case (CSS). This tool handles all the conversions.

Available Formats

  • camelCase: myVariableName
  • snake_case: my_variable_name
  • PascalCase: MyVariableName
  • kebab-case: my-variable-name

Understanding Text Case Conventions

Programming languages use different naming conventions: camelCase for JavaScript variables, PascalCase for classes, snake_case for Python, and kebab-case for CSS. Title Case and Sentence case are used in writing and publishing. Each convention serves specific purposes and following them improves code readability and maintainability.

Our converter uses PHP's multibyte string functions, ensuring proper handling of Unicode characters including accented letters, Greek, Cyrillic, and other alphabets. This means "café" correctly becomes "CAFÉ" in uppercase, preserving the accent.

Frequently Asked Questions

What's the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every word (Hello World). Sentence case only capitalizes the first letter of the sentence and proper nouns (Hello world). Title case is common for headlines; sentence case is used in body text.

Which naming convention should I use in programming?

Follow your language's conventions: camelCase for JavaScript/Java variables, PascalCase for classes, snake_case for Python/Ruby, SCREAMING_SNAKE_CASE for constants. Consistency within a project matters more than the specific choice.

Does the converter handle special characters?

Yes. Numbers, punctuation, and special characters are preserved unchanged. Only alphabetic characters are affected by case conversion. Accented characters and international alphabets (Greek, Cyrillic, etc.) are fully supported.

Can I convert between camelCase and snake_case?

Our basic converter handles UPPER, lower, and Title. For camelCase/snake_case conversion, you'd typically use code editors or programming libraries that can detect word boundaries by uppercase letters or underscores and convert between formats.
