Searching for demo data of wordpress themes [closed]

I like to have demo data of some WordPress site like Real Estate Website site as you can see here: enter image description here

So Do yo know any mechanism to scrap the demo data of one wordpress online demo site, or i must find and upload the demo files into the word press by googling and finding those data?

Is there any website as reference for demo data of WordPress sites to do that faster?

Thanks.
