is there any chrome extension or osclass plugin which help us for drop shipping or affiliate marketing in which we can auto copy data from any website and past it in our osclass

unfortunately no.
you need to get data to at least csv, json or xml and use ad importer.

is there any plugin or chrome extension which provide data and we will use your plugin for that

I am not aware, you need some crawler to get these data or use their RSS/channel if it is available.
