yep, Python + selenium or BeautifulSoup to scrape, just save it to a notepad file as a CSV then open with excel and saves as xlsx. No need to worry about programming the excel side of it then.
A quick google shows this: http://webscraper.io/
I wonder if there is a way to access the "anwaltssuche_vcard" directory and pull all the .vcf files from there.
It looks like they have protection built into the website to stop scraping. When I test this tool I get an "I am not a robot" form to fill out.
Phew, your response came just in time!If you don't want to do any coding yourself, you could use GrabzIt's Web Scraper. It is completely online and scrapes are created in a point and click way.
