FAQ
- Does it support deep objects?
- Yes, it recursively processes deep JSON arrays and nested key-value pairs.
- What happens to keys that start with a number or contain odd symbols?
- Keys starting with digits or mixing in hyphens and spaces are still detected and converted, but the result may not follow valid JavaScript identifier rules — double-check that the converted keys work fine in your actual code.
