The Complete Guide to Text Case Conversion

What is Text Case?

Text case refers to the capitalization pattern of letters in text. Different professions and contexts require different text case formats — programming languages have strict naming conventions, editorial style guides dictate heading formats, and URL structures require specific patterns.

UPPERCASE vs lowercase

UPPERCASE (all capital letters) is used for emphasis, acronyms, constants in programming, and shouting in digital communication. lowercase is the default for most body text, programming keywords, and URLs.

Programming Case Conventions

Different programming languages have established naming conventions: camelCase for JavaScript variables, PascalCase for classes and components, snake_case for Python, and kebab-case for CSS and URLs. TextCraft handles all of these instantly.
