Convert .db to OPML?

I have a recent .db backup of my subscriptions from the android app.

My phone is broken and the screen will not turn on, and that is okay, I am not writing about that, just to make it clear that I cannot go back into the app to export as OPML.

I am no longer using a smart phone, so I would like to import my backup into Kasts or gPodder, both of which do not support .db files.

I have yet been able to find a program that supports both file types, assuming that the syntax would even be a 1:1 translation, and might not work that way.

Is there some way of converting the .db to OPML without access to a smartphone?
