CamelCase Converter

A CamelCase converter rewrites plain words into programmer-style identifiers — "hello world" becomes helloWorld — and this one produces six formats at once: PascalCase, camelCase, snake_case, kebab-case, dot.notation, and path/notation. Type or paste words above and copy whichever style your language or platform expects.

What is camel case?

Camel case is a naming convention where multi-word identifiers are joined without spaces and each new word starts with a capital letter, like userProfileName — the capitals resemble a camel's humps. Its capitalized-first-word sibling is called PascalCase (UserProfileName). Both are standard in programming because most languages forbid spaces in variable names.

How this CamelCase converter works

Type plain words and the tool splits your input on whitespace into word tokens, stripping punctuation and symbols first (so "user's data!" becomes the words "users" and "data"). It then rebuilds the tokens six ways: capitalizing every word for PascalCase, lowercasing the first word for lowerCamelCase, and joining with underscores, hyphens, dots, or slashes for the other four. Whether you need a camel case generator, a pascal case converter, or a snake case and kebab case converter, this one page covers all of them — digits stay attached to their word, so "level 2" becomes level2 in camelCase and level_2 in snake_case.

All six transformations are pure string operations executed in your browser via the page's converter engine — no server, no delay, no data leaving your device.

Worked example: convert to camelCase and friends

Input: hello world example. One input, six copy-ready outputs:

Style	Output	Where you'll see it
PascalCase (UpperCamelCase)	HelloWorldExample	Class names in Java, C#, Python
lowerCamelCase	helloWorldExample	Variables in JavaScript, Java
snake_case	hello_world_example	Python variables, Ruby, SQL columns
kebab-case	hello-world-example	URL slugs, CSS classes, HTML attributes
dot.notation	hello.world.example	Java packages, config keys
path/notation	hello/world/example	File paths, route segments

How to use this tool

1. Type or paste plain words into the input field (e.g. "user profile name").
2. The tool instantly generates all six identifier styles below.
3. Copy the style your language or platform expects.
4. Note that punctuation is stripped automatically — "don't stop" becomes dontStop.

CamelCase vs PascalCase: which one do you need?

The two get confused constantly, so here is the rule of thumb used across mainstream style guides: lowerCamelCase (first word lowercase) for variables, functions, and properties — fetchUserData() in JavaScript. PascalCase (every word capitalized) for classes, types, and components — UserProfile in Java or a React component. Google's Java style, Airbnb's JavaScript guide, and PEP 8 for Python all agree on this split, and this converter gives you both from the same input so you can match any codebase.

Which case style for which language

Language / platform	Variables	Classes / types	Constants
JavaScript / TypeScript	lowerCamelCase	PascalCase	UPPER_SNAKE_CASE
Python	snake_case	PascalCase	UPPER_SNAKE_CASE
Java / C#	lowerCamelCase	PascalCase	UPPER_SNAKE_CASE
Go	lowerCamelCase (private) / PascalCase (exported)	PascalCase	PascalCase or UPPER_SNAKE
CSS / HTML	kebab-case for classes and attributes		—
URLs / file names	kebab-case (lowercase, hyphens)		—

Limitations

Honest edges: punctuation is removed rather than converted, so "don't" becomes "dont" — check possessives and contractions in identifiers by hand. Acronyms are treated as ordinary words ("API key" → apiKey, ApiKey), while some teams prefer APIKey; the tool follows the common lowercased-acronym convention and won't guess your team's rule. Non-Latin scripts pass through the splitter but won't capitalize meaningfully. And like any case tool, it cannot reverse-engineer word boundaries from an already-joined identifier — userprofilename will not split back into words.

CamelCase converter vs alternatives

Method	Best for	Watch out for
This converter	Six styles at once from plain words	One input box; manual copy per style
IDE refactor/rename	Renaming identifiers across a whole codebase safely	Overkill for a single name
Lowercase converter	Plain all-small text (pre-step for slugs)	No word-joining logic
Lodash _.camelCase()	In-code conversion inside JS projects	Requires adding a dependency
Python re one-liners	Batch-renaming files or columns	Easy to get edge cases wrong
