Frequently Asked Questions

How do I convert text to camelCase online?
Paste your text into the Case Converter and click the camelCase button. The tool converts any text format into camelCase, where the first word is lowercase and each subsequent word starts with an uppercase letter (e.g., 'my variable name' becomes 'myVariableName'). This is the standard naming convention for variables and functions in JavaScript, TypeScript, Java, and many other programming languages.
What is the difference between camelCase, PascalCase, and snake_case?
These are the three most common programming naming conventions: camelCase starts with a lowercase letter and capitalizes each subsequent word (myFunction) — used for variables and functions in JavaScript, Java, TypeScript. PascalCase capitalizes every word including the first (MyFunction) — used for class names and components in most languages. snake_case separates words with underscores, all lowercase (my_function) — the standard in Python, Ruby, Rust, and database columns. Each language ecosystem has its preferred convention, and this tool lets you convert between them instantly.
What is kebab-case and where is it used?
kebab-case separates words with hyphens, all lowercase (my-component-name). It's called kebab-case because the hyphens look like a kebab skewer. It's the standard naming convention for CSS class names, URL slugs, HTML attributes, file names in many web projects, and component names in frameworks like Vue and Angular. Since hyphens are not valid in variable names in most programming languages, kebab-case is primarily used in markup, stylesheets, and URLs rather than code.
Can I convert text to UPPER CASE or lower case?
Yes — UPPER CASE and lower case are two of the 12 available formats. UPPER CASE converts all characters to uppercase (HELLO WORLD), useful for headings, constants, and emphasis. lower case converts everything to lowercase (hello world). The tool also supports Title Case (Hello World — capitalizes the first letter of each word) and Sentence case (Hello world — capitalizes only the first letter of the first word), which are useful for formatting headings and titles according to style guides.
Does case conversion work with non-Latin characters?
Yes — the converter handles Unicode text correctly, including Cyrillic (Russian, Ukrainian), Greek, Turkish (with special i/I handling), German (eszett to SS), and other scripts that have uppercase/lowercase distinctions. For scripts without case distinction (Chinese, Japanese, Korean, Arabic, Hebrew), the structural conversions like snake_case and kebab-case still work by inserting separators between words.
