In my opinion, this is a very dangerous way of storing the information which is necessary to access your electronic wallets. Google documents are easy to crack: due to the cloud, they are synchronized on all devices where your account is open, so accessing this information becomes much easier. I adhere to the "old school" option - I store information about passwords, secret phrases and keys "on paper" - in several notebooks, which I have access only.
