What Is PascalCase Converter?

A PascalCase converter transforms text into PascalCase (also called UpperCamelCase), where every word starts with a capital letter and words are joined without separators. Developers working with object-oriented programming languages, such as C# or TypeScript, use it to adhere to the standard naming convention for class names, React/Vue components, interfaces, and types. One specific problem it solves is converting text from other formats, like camelCase or kebab-case, to Pascal case, which helps distinguish types and classes from variables and functions in code.

The tool is particularly useful when working with large amounts of text that need to be converted to the PascalCase naming convention, such as when refactoring legacy code or generating new components. What makes this tool different is its ability to split words based on specific patterns, like uppercase letters, underscores, hyphens, and periods, before converting them to Pascal case. This is achieved through a combination of regular expressions, such as replacing occurrences of `[a-z][A-Z]` with `$1 $2`, and string manipulation functions.

When using it to convert text to PascalCase, the tool processes input line by line, splitting each line into words based on whitespace and other separators, then converts each word to title case before joining them together. For example, "user account" becomes "UserAccount", and "get-user-data" becomes "GetUserData". This results in a consistent output format that follows the PascalCase convention, making it easier to write PascalCase code that adheres to this standard naming convention.

Why Use PascalCase Converter?

  • Standard convention for class names, interfaces, and React components
  • Converts from any format — spaces, hyphens, underscores, or mixed case
  • Essential for consistent code style across projects
  • Handles batch conversion of multiple names
  • Instantly usable for TypeScript types and interfaces

Common Use Cases

React Components

Convert descriptions to PascalCase for React component file and function names.

Class Definitions

Create properly formatted class names in Java, C#, Python, TypeScript, and other OOP languages.

TypeScript Types

Format interface and type names following TypeScript naming conventions.

File Naming

Generate PascalCase file names for component-based frameworks like React and Angular.

Technical Guide

PascalCase conversion splits input into words using the same word-boundary detection as camelCase (spaces, hyphens, underscores, case transitions), then capitalizes the first letter of every word (including the first one) and lowercases the remaining letters, finally joining without separators. The key difference from camelCase is that the first word is also capitalized. The algorithm handles edge cases like consecutive uppercase letters, numbers within words, and mixed separators. The output is always a valid identifier in most programming languages when the first character is a letter.

Tips & Best Practices

  • 1
    PascalCase is required for React component names — lowercase names are treated as HTML elements
  • 2
    Use PascalCase for TypeScript interfaces (IUserProfile) and types (UserData)
  • 3
    C# uses PascalCase for public methods and properties
  • 4
    Some style guides prefix interfaces with "I" in PascalCase (IRepository)
  • 5
    Angular uses PascalCase for component, service, and module class names

Frequently Asked Questions

Q What is PascalCase?
PascalCase capitalizes the first letter of every word and joins them without separators: UserProfile, GetAllUsers, HttpClient.
Q When should I use PascalCase vs camelCase?
Use PascalCase for class names, interfaces, types, and React components. Use camelCase for variables, functions, and methods.
Q Is PascalCase the same as UpperCamelCase?
Yes, they are the same thing. PascalCase is the more commonly used term.
Q Do all programming languages use PascalCase?
Most OOP languages use PascalCase for class names. Python also uses it for classes despite preferring snake_case elsewhere.
Q How are numbers handled?
Numbers within words are preserved. "user2profile" becomes "User2Profile".
