What is Text Case Conversion?
Text case conversion is the process of changing the capitalization and spacing of a string of text. Different programming languages, styling guides, and data formats often require specific naming conventions. Our free online case converter allows you to instantly switch your text between various standard formats without manually rewriting anything.
Supported Text Cases
- UPPERCASE: All letters are capitalized (e.g.,
HELLO WORLD). Often used for emphasis or SQL keywords. - lowercase: All letters are strictly lowercased (e.g.,
hello world). - Title Case: The first letter of every major word is capitalized (e.g.,
Hello World). Typically used for headings, book titles, and article names. - Sentence case: Only the first letter of the first word is capitalized (e.g.,
Hello world). Commonly used in standard prose. - camelCase: Spaces and punctuation are removed, and the first letter of each word (except the first) is capitalized (e.g.,
helloWorld). Widely used for variable names in JavaScript, Java, and C++. - PascalCase: Similar to camelCase, but the very first letter is also capitalized (e.g.,
HelloWorld). Often used for classes and components in C# and React. - snake_case: Spaces are replaced with underscores and all letters are lowercased (e.g.,
hello_world). The standard for variable and function names in Python and Ruby. - kebab-case: Spaces are replaced with hyphens and all letters are lowercased (e.g.,
hello-world). Commonly used in URLs and CSS class names. - CONSTANT_CASE: Spaces are replaced with underscores and all letters are capitalized (e.g.,
HELLO_WORLD). Used for defining constant values in most programming languages.
