Hi peerke63,
Unfortunately, SkyWallet doesn't provide a public link for their desktop app (as it supports export), only users who purchased their Windows Phone can request a download link via email. So, we purchased an copy of SkyWallet for Windows Phone and requested for download link. But we got no response from their side after two weeks. Without desktop app it won't be feasible for us to develop & test SkyWallet import.
However the best workaround at the moment is to create your own custom csv by editing the SkyWallet’s exported file. Open that in a spreadsheet program and copy columns to a new CSV with format described in this FAQ. https://www.enpass.io/kb/i-want-to-import-database-from-other-password-manager-but-its-not-present-in-enpass-import-list-can-i-still-import-my-database/
After that you will be able to import your passwords using Generic CSV importer.
