Export documents from Google Docs to server?

Question

Google

Hello, you need to make it so that in Google Docs you can select any text or part of the table, and this selected part would be transferred to the newly created page. Can you tell a newbie where to start? I can create a page using frames, but this only works with documents that have already been downloaded. There is an idea, first download to the server, and only then use the documents.
