Adding addresses to a spreadsheet via scraping the Google Knowledge graph or similar

I'm looking for a way to update an Excel /Google Sheets table containing company names with their respective postal addresses and other information available via a Google search (e.g. in the Google Knowledge Graph). I know there is a function for that in Google Sheets (importxml), however, I cannot master the function enough to retrieve the address info. That's where you come into play It would be preferable to be able to extend the functionality to other information, but the main goal is to scrape whatever info is availabe in the Knowledge Graph, especially the Companies address. I have included an example spreadsheet in the project.
