Understanding Text Case Formats

UPPERCASE

UPPERCASE converts every letter in your text to capital letters. This format is often used for emphasis, headings, acronyms, or shouting in digital communication. Example: "HELLO WORLD"

lowercase

lowercase converts every letter to small letters. This is the standard format for most body text and is often used for normalization and consistency. Example: "hello world"

Title Case

Title Case capitalizes the first letter of every major word. This format is commonly used for book titles, article headlines, and section headings. Example: "Hello World"

Sentence case

Sentence case capitalizes only the first letter of the first word in each sentence. This is the standard format for most written English prose and paragraphs. Example: "Hello world. This is a sentence."

camelCase

camelCase removes spaces and capitalizes the first letter of each word except the first word. This format is widely used in programming for variable names in JavaScript, Java, and other languages. Example: "helloWorld"

PascalCase

PascalCase is similar to camelCase but capitalizes the first letter of every word. This format is commonly used for class names in programming languages like C#, Java, and TypeScript. Example: "HelloWorld"

snake_case

snake_case replaces spaces with underscores and uses all lowercase letters. This format is popular in Python for variable and function names, as well as in database column names. Example: "hello_world"

kebab-case

kebab-case replaces spaces with hyphens and uses all lowercase letters. This format is commonly used for URL slugs, CSS class names, and HTML data attributes. Example: "hello-world"

CONSTANT_CASE

CONSTANT_CASE uses all uppercase letters with underscores between words. This format is used in programming for constants and environment variables. Example: "HELLO_WORLD"
