It converts JSON keys between snake_case and camelCase so you can use API data directly in JavaScript without manual renaming. It is designed for Axios users who need consistent key casing in requests and responses.
Does it work with nested objects and arrays?
Yes. The converter recursively processes nested objects and arrays, converting every key to camelCase while preserving values and structure.
Can I use this with Axios interceptors?
Absolutely. Paste the converted JSON into your Axios interceptor logic, or use the output as a reference to implement automatic key transformation in your app.

No. All conversion happens locally in your browser. Your JSON never leaves your device.
