Fix: Check the JSON carefully and use the correct top-level or nested path.
Fix: Use exact object key paths only and handle array-specific transformations separately.
It deletes selected keys from a JSON object and returns the cleaned result.
Yes. Nested paths like user.password can be removed when the structure matches.
