Text Case Formats Explained

Different programming languages, design systems, and writing contexts require specific text formats. Understanding when to use each case is essential for developers, writers, and content creators.

Programming Cases

• camelCase — First word lowercase, subsequent words capitalised. Standard for JavaScript variables and function names: myVariableName.
• PascalCase — Every word capitalised. Used for class names in Java, C#, TypeScript: MyClassName.
• snake_case — Words separated by underscores, all lowercase. Python variable convention and database column names: my_variable_name.
• kebab-case — Words separated by hyphens. CSS class names, HTML attributes, URL slugs: my-component-name.
• SCREAMING_SNAKE_CASE — Constants in most languages: MAX_RETRY_COUNT.

Writing Cases

• Title Case — Major words capitalised. Used in headlines, book titles, article headings.
• Sentence case — Only the first letter of the sentence is capitalised. Standard for UI labels and descriptions.
• UPPERCASE — All capitals. Used for emphasis, acronyms, or button labels.
• lowercase — All lower. Used in some design systems for a modern, minimalist aesthetic.

Alternating & Fun Cases

Alternating case (aLtErNaTiNg) is sometimes used for emphasis in informal communication. Reversed text is occasionally used for puzzles, watermarks, or decorative purposes.

Practical Uses

This tool is useful for: renaming files for web upload (spaces → hyphens), preparing variable names when refactoring code, converting spreadsheet headers to snake_case for databases, and normalising text pasted from multiple sources with inconsistent casing.
