What's the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter and capitalizes each subsequent word (e.g., 'helloWorld'). PascalCase capitalizes every word including the first (e.g., 'HelloWorld'). Use camelCase for variables/functions in JavaScript, and PascalCase for class/component names.

Title Case capitalizes the first letter of every major word (nouns, verbs, adjectives, adverbs) while keeping minor words (articles, prepositions, conjunctions) lowercase. The first and last word are always capitalized regardless.

When should I use snake_case vs kebab-case?

snake_case (e.g., 'my_variable_name') is common in Python, Ruby, and database column names. kebab-case (e.g., 'my-variable-name') is used in URL slugs, CSS class names, HTML data attributes, and command-line flags. Choose based on your project's language conventions.

Is my text sent to a server?

No. All case conversion happens entirely in your browser using JavaScript. Your text is never uploaded, stored, or transmitted anywhere.

Does the tool handle non-English text?

Yes. The tool supports accented characters (é, ü, ñ, etc.) and handles them correctly in uppercase/lowercase conversions. Title Case and Sentence Case work with basic punctuation. Code-style conversions (camelCase, snake_case, etc.) treat non-alphabetic characters as word separators.
