Writing PVA multiple variables to an excel at the end of chat (PVA) session

[Anonymous]

Hi 

I am a newbie using MS Power tools. Need help with the below scenario. 

I have set up a chatbot using MS Power Virtual Agent. I am collecting chat question responses in variables (multiple variables are used ) in Power virtual agent.

 I want to write the responses to an excel after the chat is over. How do I store it in an array-like variable and write after the end of the chat?

Currently, I am collecting a single response and writing in excel, and then coming back to chat. This back and forth is taking long time. 

Is there a way to do it more gracefully.?
