PascalCase Converter
PascalCase capitalizes every word and removes separators—perfect for type names, React components, and other constructs that read like proper nouns in code. It shares word-splitting rules with camelCase, so switching between the two stays predictable.
Example
Input
HTTP server response handler
Output
HttpServerResponseHandler
How the conversion works
The splitting rules match camelCase (spaces, hyphens, underscores, camel boundaries, acronyms). The only change is that the first word is capitalized too, so “user profile card” becomes UserProfileCard. That tiny difference is what most component and class naming conventions expect in frontend and OOP codebases. Empty lines in a list stay empty, which helps when only some rows in a table need converting. The first word is capitalized; otherwise the splits match camelCase exactly.
When PascalCase helps
Use it for classes, enums, React/Vue components, and exported TypeScript types or interfaces. Avoid it for regular variables if your style guide prefers camelCase there. In file names, teams often mirror the export: UserProfileCard.tsx exporting UserProfileCard. File names often mirror the exported symbol so imports stay obvious.
Unicode letters and cleanup
Accented letters count as word characters, so names like “naïve parser” become NaïveParser rather than being stripped. Symbols still act as separators and disappear from the final identifier. After converting, skim for leading digits—some languages disallow them even though this tool preserves the digit chunk. Leading digits are preserved as segments, but some languages still forbid them in identifiers.
Common use cases
- Scaffolding React component file names
- Naming C# or Java classes from plain phrases
- Generating enum member prefixes
- Turning feature titles into type names
Frequently asked questions
Is PascalCase the same as UpperCamelCase?
Yes. Both mean every word starts with a capital and separators are removed.
How is HTTPServer handled?
It splits into Http + Server, yielding HttpServer after PascalCase is applied.
Can I keep an interface “I” prefix?
Add the prefix yourself after converting, or include it in the input as its own word (for example “I user service”).
Does conversion upload my code?
No. Everything runs locally; use Copy or Download when you are ready to paste elsewhere.
