This tool converts snake_case identifiers into camelCase, ideal for switching between coding conventions — in your browser.
How to use it

- Underscores trigger capitalisation.
- Copy the camelCase result.
About snake_case to camelCase
Different languages favour different naming conventions — Python and databases use snake_case, while JavaScript favours camelCase. This tool converts snake_case identifiers to camelCase by removing underscores and capitalising the following letter. It is handy when porting code or mapping database fields to JS, and it runs entirely in your browser.
FAQ
Does it handle multiple words?
Yes — every underscore-separated segment after the first is capitalised and joined.
What about leading underscores?
Leading underscores are treated literally; clean them first if you want pure camelCase.
How do I go back to snake_case?
Use the camelCase to snake_case tool for the reverse conversion.
