Pascal Case Converter
Convert text to PascalCase - commonly used for class names in OOP
What is the PascalCase Converter?
The PascalCase Converter fuses words into a single identifier with every word capitalized and no separators: "user profile settings" becomes UserProfileSettings. It is camelCase's taller sibling — the only difference is that opening capital letter.
That leading capital carries meaning in code: across Java, C#, Python and TypeScript, PascalCase marks types — classes, interfaces, enums and, in React, components. When a reviewer sees OrderProcessor, they instantly know it is a blueprint, not a variable. The converter lets you generate such names from plain phrases without thinking about the rules.
How to use
- Type the concept as separate words, e.g. "order processor service", into the input.
- Convert — each word is capitalized, spaces and separators are removed, and the words are joined.
- Check that acronyms landed the way your codebase prefers (
HttpsClientvsHTTPSClient) and adjust if needed. - Copy the identifier into your class, interface or component declaration.
Common use cases
- Object-oriented design — naming classes in Java, C# and Python per PEP 8's CapWords convention.
- React development — creating component names, which must start uppercase for JSX to treat them as components.
- TypeScript types — defining interfaces, enums and type aliases in the community-standard style.
- Database modeling — drafting entity and table-class names before mapping them to snake_case columns.
Example
Input: order processor service Output: OrderProcessorService
FAQs
What is the difference between PascalCase and camelCase?
PascalCase capitalizes the first word too (UserProfile); camelCase leaves it lowercase (userProfile). By convention, types and classes get PascalCase while variables, functions and properties get camelCase.
Why do class names start with a capital letter?
It is a visual contract: in user = User(), the capital instantly tells the reader which side is the class and which is the instance. The convention dates back to Smalltalk and spread through Java and C#.
How should acronyms be handled?
Style guides disagree — .NET prefers HttpsClient (only first letter capped) while some codebases write HTTPSClient. Pick your project's rule and stay consistent; the converter capitalizes the word normally, so tweak acronyms afterward.
Can the output start with a number?
No valid identifier can, and the converter will not produce one from clean input. If your phrase begins with a digit, add a leading word first — "3d renderer" should become something like Renderer3d or be renamed.
