Hi Randy,
Sorry you're having trouble with the Requirement Export. I haven't heard of any issues with multiple lines in the Description (or other text) fields. Your data should be exporting with the entire contents, including line breakd, for all of the text fields.
If you're having trouble, would you mind letting our Support Team know? Just click on the Help Center link at the top right of your screen, then click Create Support Ticket, and send them an example CSV file so we can get it fixed up for you.
We do have Ad-Hoc reports that generate a spread-sheet like report for you. On the Reports tab, look for Ad-Hoc Detail, then look for the Requirements report. On this report you can decide which fields you want, you can filter the data, and then save it as a spreadsheet.
Let me know how it goes!
