Web Scrapping - Crawling for an 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. Web Crawling can be done using Python but it need to be executable (exe) file. I will need the source code at the end of the project. The python script need to run in the background without any interruption. It is ok to show a command prompt while the script is running. The software need to have the option of choosing which categories or sub-categories not to scrap. Also, the software need to have the option to enter number of days and delete the records in the excel file that are older than those number of days. Finally, the file need to be in exe or any format that can be schedule using the Windows Task Scheduler.
