Membership 2 Pro: How to export users

I imported quite a few users from another membership application. After importing, I subscribed them to a subscription with a 1 year expiration so dates were set to 1 year from subscription date. However, the users I imported have varying expiration dates. I was thinking of exporting them, setting the dates in Excel and re-importing them. But I can't figure out how to export. Do I have to go into the database to do it? Is there an easier solution to my problem?
