Exporting wordpress posts with custom fields?

Question

WordPress

Hello guys!
The site has standard posts (records) with custom fields! It is necessary to unload the filled data from arbitrary fields, into a table or into txt. So is it possible at all?
I saw an article written on the site and there was a button - PRINT, it's about the same functionality,
I don't have to display it in the frontend! The main thing is that I could upload all the posts and work with this data! At this stage, I go into the post and with each field I do Ctr+c - Ctrl+v !
Ready to answer in more detail if something written is not clear!
Thank you
