That is strange. Like joemikeb said, CSV is a generic standard that any spreadsheet software can import. It might be worth a try to export into a CSV format and see what you get when you import into Excel. It should be a very quick process, export/import.
You will likely have choices to make before a CSV can be accurately imported, but the basic principles are dead simple. In my case when importing to MoneyDance 2022 from Quicken 6 I had to tell the import utility to ignore some columns.
