PascalCase Converter API: Transform Text to PascalCase

Need to convert text to PascalCase for class names, type definitions, or code generation? The PascalCase Converter API transforms any input text into proper PascalCase format, handling various input formats automatically.

What is PascalCase?

PascalCase (also known as UpperCamelCase) is a naming convention where each word starts with a capital letter and words are joined without separators. It is named after the Pascal programming language where it was commonly used.

Examples of PascalCase:

• UserAccount
• HttpRequestHandler
• GetAllCustomers

When to Use PascalCase

PascalCase is the standard convention for:

Class Names

Most programming languages use PascalCase for class and type names: class CustomerService

Interface Names

TypeScript, C#, and Java interfaces: interface IUserRepository

React Components

React components must use PascalCase: <UserProfile />

Type Definitions

TypeScript and GraphQL types: type OrderItem = {...}

Using the PascalCase Converter API

TinyFn provides a simple endpoint to convert text to PascalCase:

POST https://api.tinyfn.io/v1/transform/pascalcase
Headers: X-API-Key: your-api-key
Content-Type: application/json

{
  "text": "user account settings"
}

{
  "original": "user account settings",
  "pascalcase": "UserAccountSettings",
  "word_count": 3
}

Parameters

Supported Input Formats

The API handles various input formats automatically:

• hello world → HelloWorld
• hello-world → HelloWorld
• hello_world → HelloWorld
• helloWorld → HelloWorld
• HELLO_WORLD → HelloWorld

Code Examples

JavaScript / Node.js

const response = await fetch(
  'https://api.tinyfn.io/v1/transform/pascalcase',
  {
    method: 'POST',
    headers: {
      'X-API-Key': 'your-api-key',
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ text: 'user_profile_component' })
  }
);
const { pascalcase } = await response.json();
console.log(pascalcase); // UserProfileComponent

Python

import requests

response = requests.post(
    'https://api.tinyfn.io/v1/transform/pascalcase',
    headers={'X-API-Key': 'your-api-key'},
    json={'text': 'get-all-customers', 'preserve_acronyms': True}
)
result = response.json()
print(result['pascalcase'])  # GetAllCustomers

cURL

curl -X POST "https://api.tinyfn.io/v1/transform/pascalcase" \
  -H "X-API-Key: your-api-key" \
  -H "Content-Type: application/json" \
  -d '{"text": "user account settings"}'

Common Use Cases

• Code Generation: Convert database table names to class names
• React Development: Create component names from descriptions
• API Design: Generate type names from field descriptions
• ORM Tools: Convert snake_case table names to PascalCase models
• Documentation: Standardize naming in auto-generated docs

Best Practices

1. Be consistent: Use PascalCase for all types/classes in a project
2. Handle acronyms carefully: Decide on HTTP vs Http and stick with it
3. Clean input first: Remove special characters before conversion
4. Validate output: Ensure generated names are valid identifiers
5. Document conventions: Establish team guidelines for edge cases
