How to save all correspondence from a VK conference to a text document?

Question

Browsers

There is a VKontakte conference for 6k+ messages, I need to save everything in text \ any other format so that I can read them leisurely.
What utility can do this, is it possible at all?
I did not dare to download suspicious software myself, maybe they will help here.
Thanks in advance for any advice.

iMacros for example. You just need to write a script for it, but it's easy there. Find any class or id and save the data to an external file. I could write to you in 5 minutes, but I don't have an account.
