We'll have another solution in the not too distant future that should cover things and be a documented format that anyone with the know how could use.
Also important to note, that if your account ever lapses due to lack of payment. The account is still read-only. You can export your data if you wish even when the account is read-only. We do not lock you out of your data, we just prevent normal use of the application (browser extension, editing items, adding new items, etc). But the data you've already entered is entirely accessible if you want to copy/paste or export.

I don't think anyone who uses a password manager is exporting to CSV for security purposes.
I moved away from 1password at the time of the subscription palaver. I managed to move everything to Keepass but each entry has it's own folder.
I don't blame 1Password for the state of my Keepass db (although they pretty much forced my hand) but the closed nature of 1Password does bite you in the arse when you decide to leave.
