Text Case Formats Explained
UPPERCASE
Converts every letter to capitals. Useful for acronyms, headings, warning labels, or design work where ALL CAPS creates visual impact.Example: hello world → HELLO WORLD
lowercase
Converts every letter to small letters. Useful for usernames, hashtags, or informal writing styles.Example: Hello World → hello world
Title Case
Capitalizes the first letter of each major word. This is the standard format for article titles, book titles, and headings in English.Example: the quick brown fox → The Quick Brown Fox
Sentence case
Capitalizes only the first letter of the first word in each sentence — exactly how normal written sentences look.Example: HELLO WORLD. HOW ARE YOU. → Hello world. How are you.
camelCase
Removes spaces and capitalizes the first letter of each word after the first. Widely used in programming for variable names.Example: first name → firstName
PascalCase
Like camelCase, but capitalizes the first word too. Common in class names and component names in code.Example: user profile → UserProfile
snake_case
Replaces spaces with underscores and uses all lowercase. Standard in Python programming and database column names.Example: user profile name → user_profile_name
kebab-case
Replaces spaces with hyphens and uses all lowercase. Commonly used in URLs and CSS class names.Example: user profile name → user-profile-name
