camelCase Converter

Convert text or identifiers to camelCase instantly.

This tool runs entirely in your browser. Your files are never uploaded to a server.

Turn a word sequence into a camelCase identifier: the first token is lowercase, every later token gains an uppercase initial, and no separator remains. Tokenization recognizes whitespace, `_`, `-`, `.`, `/`, lowercase-to-uppercase boundaries, and the end of an acronym before a normal word, so `APIResponse/user_id` becomes `apiResponseUserId`. Every token is lowercased first, meaning original casing and all-cap acronym styling are not retained. Other punctuation does not automatically split a token. The result is produced locally for copying; the tool does not check reserved words or identifier rules for any programming language.

Frequently Asked Questions

What is camelCase used for?
It's the standard naming convention for variables and functions in JavaScript, Java, and many other languages — the first word is lowercase and each following word starts with a capital letter.
Can I convert from snake_case or kebab-case to camelCase?
Yes — the tool splits your input on underscores, hyphens, dots, spaces, and existing camelCase/PascalCase boundaries before rejoining it in camelCase, so it works starting from any of those styles, not just plain text.
Does it handle acronyms like "URL" or "ID" correctly?
Acronyms are treated as a single word and capitalized like any other word in the sequence, so "user_id" becomes "userId" and "parse_url" becomes "parseUrl".
