Yes, there is a way. Access the following address (adjust the activityType and activitySubType accordingly, or remove them, if you do not wish to filter by them), and the copy the JSON code and conver it to CSV (or Excel) for example at http://convertcsv.com/json-to-csv.htm
connect.garmin.com/modern/proxy/activitylist-service/activities/search/activities?activityType=cycling&activitySubType=mountain_biking
This is a hack, not an official function, hence there is no documentation. If you need more parameters, you need to analyze the network communication of Garmin Connect Web (for example in Chrome's DevTools), to see how it exactly works, just like I did to give you this example.
