FAQ

What is camelCase?

camelCase is a naming convention where the first word is lowercase and subsequent words start with an uppercase letter, with no spaces or separators. Example: firstName, apiResponse, createdAt.

Can I convert snake_case or kebab-case to camelCase?

Yes. Paste any snake_case, kebab-case, or space-separated text and it will be converted to clean camelCase. Underscores, hyphens, and spaces are all treated as word boundaries.

Does this work on JSON keys?

It works on keys as text. For a full JSON object with nested keys, consider using a JSON formatter or a dedicated JSON key transformer. This tool is ideal for individual keys, code identifiers, and small key lists.

Is my code or data sent to a server?

No. The conversion happens entirely in your browser. Your input is never uploaded to a server, so you can safely use even sensitive code snippets and object keys.

Example input

Try it with this sample — paste it into the box above:
