Hi @anon49707162, welcome to the Asana Community Forum!
If you wish to have your form submissions stored in a CSV file, you can create a report of all form submissions on a specific project and export it to CSV. You can also save this report.
In this thread you can find how to search for all form submissions: Search for “Added by Form”, and you can also find all the steps to save and export your report in this article.
Lastly, we already have a thread in our #productfeedback category related to your second request. I suggest you to support this request adding your vote here: Forms: Ability to have questions trigger a task/subtask creation & option to share/manipulate at form level
We have recently launched some updates for Forms, if you are interested, have a look at the announcement here: Forms are now even more powerful and customisable!
I hope this helps, @anon49707162! Let me know if you have any other questions
