PascalCase (also called UpperCamelCase) is a naming convention where the first letter of every word is capitalized and words are joined without separators. For example: MyVariableName, UserProfile, HttpResponse.

What is the difference between PascalCase and camelCase?

The only difference is the first letter: PascalCase capitalizes it (MyVariable), while camelCase keeps it lowercase (myVariable). PascalCase is used for class names and types; camelCase is used for variables and functions.

What Is PascalCase?

PascalCase vs camelCase

Convention	Example	First letter	Used for
PascalCase	`MyVariable`	Uppercase	Classes, types, components
camelCase	`myVariable`	Lowercase	Variables, functions, methods

Where PascalCase Is Used

C# / .NET — classes, methods, properties, namespaces
Java — class names and interfaces
React / Next.js — component names (UserProfile, NavBar)
TypeScript — interfaces, types, enums
Go — exported (public) identifiers
Swift — types, protocols, enum cases
Kotlin — classes and objects

Convert snake_case to PascalCase

Paste your snake_case text (e.g., user_first_name) into the converter above. The tool splits on underscores and capitalizes each word to produce UserFirstName.

Convert kebab-case to PascalCase

Similarly, kebab-case input like my-component-nameis converted to MyComponentName. This is useful when converting CSS class names or URL slugs to React component names.

FAQ

Is PascalCase the same as Title Case?

No. Title Case keeps spaces between words (“My Variable Name”) while PascalCase removes them (MyVariableName). Title Case is for human-readable text; PascalCase is for code identifiers.

When should I use PascalCase vs snake_case?

Follow your language's convention. C#, Java, and TypeScript types use PascalCase. Python and Ruby use snake_case for most identifiers. Mixing conventions in the same codebase is considered bad practice.
