Convert any text to camelCase — plus PascalCase and back — in one click.
The Camel Case Converter transforms words, phrases, and identifiers into clean camelCase. Paste text separated by spaces, hyphens, or underscores — or an identifier already written in another convention — and get properly formatted camelCase output for variables, object keys, and API fields. It saves you from renaming things by hand and keeps naming consistent across a codebase.
camelCase joins multiple words into one token with no separators, lowercasing the very first word and capitalising the first letter of every word after it — producing names like firstName, totalItemCount, or isUserActive. The little humps of capital letters in the middle are why it is called camelCase. It is the default naming style for variables and functions in JavaScript, Java, Swift, and many other languages.
Consistent identifier naming is one of the quiet foundations of readable code. When every variable, property, and function follows the same convention, developers can scan a file without pausing to decode inconsistent styles, and tooling such as linters and autocompletion works more predictably. Mixing styles — a user_name here and a userName there — creates friction, invites bugs when names are mistyped, and makes a codebase feel unmaintained. A converter removes that friction by producing one canonical style every time.
Watch how different inputs normalise to the same clean result:
user first name → userFirstNameuser_first_name → userFirstNameUser-First-Name → userFirstNameWhatever separators or casing you start with, the converter collapses them into a single, consistent camelCase token you can paste straight into your code.
These conventions differ only in casing and separators, but each has a home. camelCase (myValue) lowercases the first word and is standard for variables and functions in many C-style languages. PascalCase (MyValue) capitalises the first letter too and is conventional for class and type names. snake_case (my_value) uses underscores and dominates Python, Ruby, and SQL. kebab-case (my-value) uses hyphens and appears in URLs and CSS. Choosing the right one keeps your code idiomatic for its language and framework, which is exactly why quick conversion between them is so handy.
A naming style that joins words with no spaces, lowercasing the first word and capitalising each following word, e.g. myVariableName.
PascalCase capitalises the first letter too (MyVariableName); camelCase leaves it lowercase.
Yes — mixed separators and inconsistent casing are normalised into clean camelCase.
Yes. Underscored identifiers convert directly, e.g. first_name becomes firstName.
Yes — digits are preserved in place while the surrounding words are cased correctly.
No. Conversion happens entirely in your browser.
