Unnecessary inline import with unconventional private alias

Low Severity

The json module is imported inside the function body with an unnecessary underscore-prefixed alias (_json). There is no naming conflict with json in this scope, making the alias pointless and misleading (the underscore prefix conventionally denotes a private/internal name). The import also belongs at the module level alongside pickle, yaml, and marshal rather than being repeated on every call to import_data.
