I just opened Plantstep, and took a quick look. While I had a cultivar on the page, I clicked on "report", which is at the bottom, fourth from the left. One of the options is "Export to Excel". I do not know if you would have to do this for each cultivar, or if you can export all of them at once. I would suggest contacting the person who created the program for technical advice on that. There must be a way to do it! I'm too tired to play with it, but it's probably something easy to do.
