Case Checker CS (C# Naming Case Checker)

Paste C# identifiers (one per line) to detect their case and verify they match a chosen C#-style casing. You can also convert names to a target style in one click.

Tip: paste mixed styles (camel/snake/kebab) and convert them to the style you want.

FAQ

    
What does “case checker cs” mean here?
It’s a case checker focused on common C# identifier casing: PascalCase, camelCase, _camelCase, and SCREAMING_SNAKE_CASE.
Does this tool follow official C# naming rules exactly?
No—it's a fast heuristic checker and converter. It’s meant for quick cleanup, not a full Roslyn analyzer.
Can I paste a whole file of code?
You can, but it works best with one identifier per line. If you paste code, use Auto detect to see what it recognizes.
What counts as PascalCase vs UPPER?
PascalCase starts with an uppercase letter and contains lowercase letters (e.g., MyClass). UPPER is all caps/digits (e.g., HTTP or MAXVALUE).
How is _camelCase handled?
_camelCase is detected when a name starts with “_” followed by a lowercase letter (e.g., _myField).
Will it change my text outside the browser?
No. Everything runs locally in your browser; no network requests are made.
Can it convert kebab-case or snake_case to C# styles?
Yes. Paste names like my-name or my_name and convert them to PascalCase, camelCase, or _camelCase.
