If you are looking into sharing the archive (e.g. email it for someone else to import) and not save it to your computer or phone, use the Share option instead of Export.
To start sharing, navigate to any list and use the Share 
button.
On Mac You can also click on File ->Share in the menu bar.
From here, you'll be presented with a Share Sheet where you can share the archive by AirDrop, Mail, save it to files, or to any other app that can receive files.
