I filtered my library by type:commentary revelation and sorted by Author
I chose Print/Export and then exported to a new Excel document
The result was missing a column for Publisher.
Here's the spreadsheet that was generated:
8877.Revelation Commentaries.xlsx
Also, it's odd that the Author column, which I'd sorted by, was the 10th column. It bears no resemblance to the ordering I have of my columns in my Library (which is Rank, Cover Image, Type, Title, Publication Date, Author, and so on). I'd expect Author to either be the first column (because it was the column I sorted on) or to be in the order I have it in my Library, but the order actually exported seemed pretty random. Probably based on some internal data structure order which is inscrutable to users and non-changeable by users.
