Additionally, if the base64 decode operation returns any items that look like a base64 encoded string or file, a gzipped binary sequence, a zipped or tar archive, it will attempt to extract the contents before searching for potentially interesting IoC observables within the decoded data.\n",

This may not always be an accurate notation - it is mainly use to allow you to associate an individual row with the reference value contained in the full_decoded_string column of the topmost item).\n",
    "  - original_string - the original string before decoding.\n",
    "  - file_name - filename, if any (only if this is an item in zip or tar file).\n",

    "  - input_bytes - the decoded bytes as a Python bytes string.\n",
    "  - decoded_string - the decoded string if it can be decoded as a UTF-8 or UTF-16 string. Note: binary sequences may often successfully decode as UTF-16 strings but, in these cases, the decodings are meaningless.\n",

    "  - file_hashes - collection of file hashes for any decoded item.\n",
