Hi,
I am an experienced software and Web developer, and I am highly expert at developing Web scrapers. I understand that you want a Web scraper that automatically and periodically extracts data from a specific website that requires users to be logged in securely. The results must then be exported into an Excel spreadsheet. It would be great if you can provide more details.
Just so you know, I have already developed a plethora of Web scrapers/crawlers/bots, accessing websites such as Google (and its services), Facebook, Lenovo and a lot of other websites (some globally popular, some not), on which clients request me to develop scrapers/crawlers/bots. That's how confident I am that I can develop yours. I am a dedicated developer, and if you want to work with the best, you got to work with me.
Respectfully yours,
Mark
