How do I download a spreadsheet of my Internal Notes on each item?

First, click into your auction, and head to Items. Then, click the three horizontal lines near the top of the page to switch to Table View. 

From there, click on the bookmark icon on the far right of the page. That will allow you to toggle the fields you like to see on the table (such as Notes, FMV, Donor, and so on).

If you would like to download the information, click the download button (highlighted below) to download as a CSV.
