While the product team is still getting a gauge for the need of this feature, in the meantime this workaround may work for some.

Utilizing a suggestion by Frederick Stark, you can retrieve the JSON of that page and then convert that into a .csv file. 

I tried this, and it was relatively easy. And please note, I am most certainly not a developer. 

1. You will first need to retrieve the Page ID of your feedback page; this is in the URL of your page when you are logged into the Control Panel:

2. Once you get the pageID of your feedback page, you can use this URL to retrieve the JSON for your feedback page: 

https://SLUG.nationbuilder.com/admin/activities/page.json?id=PAGEID&page=1 

You will, of course, need to replace SLUG and PAGEID seen above with the appropriate content/information. 

3.Last you can use a tool such as https://json-csv.com/ to convert this JSON into a .csv file* You will do this by placing the JSON result in the content box on https://json-csv.com/. Once you do this, you will need to scroll down to download the .csv of the data on your page. 

* json-csv.com is not endorsed by NationBuilder. It is your responsibility to ensure that exported data is safe and that you follow local and international 3rd-party data protection laws. 

This a temporary workaround while our Product team explores the possibility of implementing a .csv download option for Feedback pages.
