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".
