Qu’est-ce que Case Converter ?
A case converter is a tool that rewrites text into a different capitalization or identifier format, such as UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, or kebab-case. These formats are conventions used across programming languages, URLs, CSS, databases, and prose, where applying the wrong case can break code or confuse readers. The converter parses pasted input by splitting on spaces, hyphens, underscores, and the boundary between a lowercase letter and a following uppercase letter, so a string like "helloWorldExample" is recognized as three separate words. It then outputs every supported format at once, so you can compare and copy whichever one your target context requires. This makes it useful when moving text between naming conventions, such as turning a title into a Python variable name or a JavaScript class name.

Erreurs courantes
- Using spaces in a variable name meant for code — always convert to camelCase, snake_case, or PascalCase depending on your language's convention first.
- Mixing kebab-case and snake_case within the same codebase or URL scheme, which makes tooling and search-and-replace unreliable.
- Assuming Title Case and PascalCase are the same — Title Case keeps spaces between words, PascalCase removes them.
