Bridge Compass offers the opportunity (through the file menu or F4) to export your deals to a pbn file. The official export format 2.1 is used.
You can also read deals from a pbn file (F3). These deals can be added to your current project, or you can start a new one. The best tab for it is Practice Deals because then you can see the deals🤓 A new project gets the name of the pbn file as you can see in the title bar of the application. The import format is loose. The only three mandatory fields are deal, board number and vulnerability.
Besides PBN you can also export a file to the Lin-format (F7). This is used by BBO so you can upload a practice set for partnership bidding. There are tools out there to convert a PBN format into Lin but the coach of the Dutch open team rather had it in this application. And he had a good point in that.
