Excellent point Will. I always just fix the spreadsheet formatting after pasting. It could be more accurate during the CSV open process. Although when I opened the CSV file in Excel 2010 just now, it didn't go through the data mapping process. Hmmm. Usually, it does.
Anyway, I didn't know you could use "File->Export Playlist" against a View, but that does work. However it doesn't respect the columns shown in the View, and just exports all Library fields for each selected file, in some predetermined sequence.
The Copy-Paste process only carries across the fields in the View and maintains the sequence.
