Getting invalid file error when we use mime_types (text/csv)

When i am going to import file(vendor.csv). Then i get invalid file error. The reason is that one record in first column data is C & G which create error if we remove space then its working. why? As you can see here in attached screenshot: screenshort of csv

Here is my code

public function import()
    {
        set_time_limit(0);
        $input = Input::all();
        $validator = Validator::make($input, ['file' => 'required|mime_types:text/csv']);

        if($validator->fails()) {
            return ApiResponse::validation($validator);
        }
}

error:

{
    "error": {
        "status_code": 412,
        "validation": {
            "file": [
                "Invalid file type."
            ]
        },
        "message": "Validation Failed"
    }
}
