About This Tool

Accidentally typed a paragraph with Caps Lock on? Need to convert article titles into proper Title Case for editorial publishing? Or refactoring code variables between camelCase, snake_case, and CONSTANT_CASE for programming languages? Manually retyping text to change letter casing is tedious and unnecessary. Our client-side Case Converter transforms text casing across a dozen standardized formats instantly. Choose from Sentence case, UPPERCASE, lowercase, Capitalized Words, Title Case (following AP or Chicago style rules), camelCase (JavaScript/Java), snake_case (Python), kebab-case (URLs/CSS), PascalCase (C#/TypeScript), and Alternating cAsE. Because all transformations take place in your browser memory using string replacement algorithms, conversion completes in milliseconds. Your text drafts and code snippets remain strictly private on your computer.
