How To Convert Text To camelCase
Learn what camelCase is, where it is used in code, and how to convert any phrase into a camelCase identifier.
Quick Answer
This camel case converter lets you convert to camelCase instantly, joining words together with no spaces, keeping the first word lowercase and capitalizing the first letter of every word after it: "user profile image" becomes "userProfileImage". It follows the standard javascript naming convention for variables and functions.
Try The camelCase Converter →Where camelCase Is Used
camelCase is the dominant convention for variable and function names in JavaScript, TypeScript, Java, Kotlin, and Swift. Its close relative PascalCase (which also capitalizes the first letter) is used for class names, React components, and TypeScript interfaces.
How The Conversion Works
The converter breaks your text into words at spaces, hyphens, underscores, and other separators (and also at existing camelCase humps) then rejoins them in camelCase. For example: "user-profile-image", "user_profile_image", and "User Profile Image" all become "userProfileImage". Each line is processed independently, so you can convert a whole list of names at once.

Why camelCase Matters For Code
Consistent naming conventions make code easier to read, search, and maintain. When a
codebase mixes camelCase and snake_case, every reader has to decide whether
user_name and userName are the same variable. Linters and type
checkers also enforce naming rules, so mismatched case produces warnings that slow down
teams. Converting names to camelCase before pasting into code prevents these issues at
the source.
Common Mistakes
camelCase vs Other Naming Conventions
camelCase is one of four common naming alternatives for code identifiers. PascalCase is identical except the first letter is also capitalised: it is used for class and component names. snake_case uses underscores as separators and is the default in Python and SQL. kebab-case uses hyphens and is used for CSS class names and URL slugs, but cannot be used for variable names in most languages because hyphens are treated as the subtraction operator. camelCase is the standard choice for JavaScript, TypeScript, Java, and Swift variables and functions.
