Pascal Case Converter
The Pascal Case Converter builds PascalCase names — every word capitalized and joined without separators — the convention for classes, components, interfaces and types in most languages. Feed it a plain description like 'user profile card' and get 'UserProfileCard'. Input can start life as snake_case, kebab-case, camelCase or plain prose; the word splitter handles all of them.
How to use Pascal Case Converter
- Type or paste a phrase or an existing identifier in any style.
- The PascalCase version appears in the result box immediately.
- Copy the name into your codebase.
Supported behavior
- Every word is capitalized, including the first.
- Words are detected across spaces, hyphens, underscores, dots and camelCase humps.
- Accents are stripped so results are valid ASCII identifiers.
Best for
- Naming React/Vue components and classes.
- Generating type and interface names from domain terms.
- Unifying names when merging codebases with different conventions.
Limits
- Acronyms become normal words: 'API response parser' becomes 'ApiResponseParser'. Rename afterwards if your style guide keeps acronyms uppercase.
- Digits are kept inside words, but a name starting with a digit is invalid in most languages.
Privacy notes

- Conversion happens in your browser; nothing is uploaded.

Pascal Case Converter FAQ
When should I use PascalCase instead of camelCase?
Use PascalCase for classes, components, interfaces and types; use camelCase for variables, functions and properties. That split is the dominant convention in JavaScript, TypeScript, Java and C#.
Does it work on existing snake_case names?
Yes — 'user_profile_card' converts to 'UserProfileCard' because underscores are word boundaries.
What happens to numbers in the phrase?
They are kept attached to their word: 'version 2 parser' becomes 'Version2Parser'.
