Is there another way to view the data than the spreadsheet below each form?

You can view the data on your form submissions page http://www.jotform.com/help/269-How-to-view-Submissions.

You can also check them in your email when you receive a submission from your form.

Or, create a report so you can access the submissions data through the report URL.
