Web Scrapping / Crawling e-commerce website

I need to web crawl e-commerce website to extract the top 100 products in each category and put the results in an excel file each day, then have a report that shows the products that remained in the top 10 (this can be adjusted to be any number of ranks) for the past 30 days (this can be adjusted to any number of ranks). Web Crawling can be done using Python but it need to be executable file.
