How to Use the Case Converter
Type or paste your text into the input area, then click any of the case transformation buttons above the output. Your text is instantly converted. You can copy the result with one click and switch between formats as needed. The tool supports twelve different text formats, from standard writing conventions to programming naming conventions.
Text Case Formats Explained
UPPERCASE and lowercase: The most basic transformations. Use UPPERCASE for acronyms, headings, or emphasis. lowercase is commonly used in modern UI design and email addresses.
Title Case and Sentence case: Title Case capitalizes every major word and is standard for headlines, book titles, and article headings. Sentence case capitalizes only the first word and proper nouns, used in most formal writing.
camelCase and PascalCase: camelCase (first word lowercase, subsequent words capitalized) is the standard for JavaScript, TypeScript, and Java variables and functions. PascalCase (every word capitalized) is used for class names, components in React, and TypeScript types.
snake_case and kebab-case: snake_case (words separated by underscores) is the Python and Ruby convention for variable and function names. kebab-case (words separated by hyphens) is standard in URL slugs, CSS class names, and HTML attributes.
Common Use Cases
Developers: Quickly convert between naming conventions when switching between programming languages or refactoring code. Convert database column names from snake_case to camelCase for JavaScript objects, or transform API response keys to match your frontend conventions.
Writers and Editors: Fix inconsistent capitalization in documents, convert headlines to Title Case for publication, or normalize formatting across contributed content from multiple authors.
