How the pascalcase converter works

  1. Text is split into words.
  2. Every word is capitalised and joined without separators.
  3. Common for class names in C#, Java and TypeScript.

Rules and edge cases

  • Every word is capitalised and joined without separators: user first name becomes UserFirstName.
  • Acronym runs collapse into a single capitalised word, so http response code becomes HttpResponseCode.
  • Digits stay in place and are not treated as word boundaries — api v2 client becomes ApiV2Client.
  • camelCase is identical apart from the lowercase first word; PascalCase is also called UpperCamelCase.

Frequently asked questions

Where is PascalCase the convention?

Class, interface, enum and type names in C#, Java, TypeScript and Swift, plus React component names and .NET method names.

Should acronyms be HTTPClient or HttpClient?

The .NET and Java guidelines both recommend HttpClient for acronyms of three letters or more, which is what this converter produces.
