camelCase Converter
camelCase joins words with no separators and capitalises every word except the first: userFirstName. Paste a sentence, a variable name, or a whole list below and click camelCase.
Example
Input
the quick brown fox jumps over the lazy dogOutput
theQuickBrownFoxJumpsOverTheLazyDogIt understands your input format
- The converter splits words on spaces, underscores, hyphens, dots, and existing capital-letter boundaries, so all of these produce
userFirstName: user first nameuser_first_name— snake_caseuser-first-name— kebab-caseUserFirstName— PascalCaseUSER_FIRST_NAME— CONSTANT_CASE
Where camelCase is the convention
- JavaScript and TypeScript — variables, functions, object properties, and JSON keys.
- Java, C#, Swift, and Kotlin — methods, fields, and local variables (types use PascalCase).
- REST API payloads consumed by JavaScript clients, where camelCase keys avoid conversion on the front end.
- Database ORM models that map snake_case columns onto camelCase properties.
Converting a whole list at once
Each line is converted independently, so you can paste an entire column of database columns or form field names and convert all of them in one click. Line breaks are preserved, which means you can paste the result straight back into your editor or spreadsheet.
