How to use the Pascal Case Converter
Convert to PascalCase in three steps:
1
Paste your phrases
Enter one phrase per line in any format — spaces, hyphens, underscores, camelCase, or snake_case.
2
Click Convert
Press 'Convert to PascalCase'. Every word's first letter is capitalised and all separators are removed.
3
Copy or download
Copy the PascalCase output to clipboard or download as a .txt file.
When to use this tool
Use PascalCase for class and component naming in code:
- →Generating React component names from feature or element descriptions
- →Creating TypeScript interface names, type aliases, and enum names
- →Converting database table names (snake_case) to ORM model class names
- →Naming C# classes, structs, enums, and .NET types following PascalCase convention
- →Generating Angular component, service, pipe, and directive class names
- →Batch-converting a list of entity or resource names to PascalCase for a new codebase
Frequently asked questions
Q:What is the difference between PascalCase and camelCase?
PascalCase capitalises the first letter of every word including the first one (HelloWorld, UserProfile). camelCase keeps the first word lowercase and capitalises subsequent words (helloWorld, userProfile). PascalCase is used for classes, React components, and TypeScript interfaces; camelCase is used for variables, functions, and object properties.
Q:Can I convert snake_case database table names to PascalCase model class names?
Yes — this is one of the most common use cases. 'user_profile_settings' becomes 'UserProfileSettings', 'order_line_item' becomes 'OrderLineItem', and so on. Enter one table name per line to batch-convert an entire schema.
Q:Does it handle acronyms like 'API' or 'URL' in PascalCase?
The converter capitalises only the first letter of each token and lowercases the rest. So 'get API key' becomes 'GetApiKey' and 'parse URL string' becomes 'ParseUrlString'. If you prefer to preserve full-caps acronyms (GetAPIKey), adjust those manually after conversion.
Q:Is PascalCase the same as UpperCamelCase?
Yes — PascalCase and UpperCamelCase are two names for exactly the same format: every word begins with a capital letter and no separator characters are used (HelloWorld). The term 'PascalCase' originates from the Pascal programming language, which popularised this convention for identifiers.
Q:Can I convert multiple phrases at once?
Yes — enter one phrase per line and all lines are converted in a single click. This is useful for rapidly generating a full set of class names, component names, or interface names from a list of plain-English descriptions or database entity names.
Q:Which languages and frameworks use PascalCase as their standard?
PascalCase is the standard for class names in JavaScript, TypeScript, Java, C#, Swift, Kotlin, and C++. React components must be named in PascalCase for JSX to treat them as custom components (lowercase names are treated as HTML elements). TypeScript interfaces, type aliases, enums, and decorators also follow PascalCase. Angular services, components, pipes, and directives use PascalCase for their class names.
