JSON Key Case

What is JSON Key Case?

Different ecosystems use different naming conventions: APIs often return snake_case, while JavaScript prefers camelCase. This tool recursively transforms all the keys of a JSON object —including nested ones— between snake_case, camelCase, PascalCase and kebab-case, keeping the values intact.

Paste an API response and adapt it in one click to your language's convention, without renaming field by field. It works on objects and arrays at any depth, and all processing is local.
