Recently, we developed an extension for both Chrome & Firefox for one of our clients who needed a quick solution of scrapping the data from a webpage. Our logic is simple: scrap the data in the format required by the clients and save that data under respective columns, in a database. This of course, can be exported to CSV or any other textual format for further usage.
Scraping contact info and comparing prices has been implemented using our plugin.
Infomaze has developed quite a few extensions for our clients until now. We will be happy to help you, were you to have a similar requirement. Feel free to contact us for an obligations-free consultation regarding your IT needs.
