Desktop EXE

We require a desktop EXE which crawls your amazon listings, and outputs their position relative to a search term in an Excel spreadsheet or CSV. Example: Look up an **ASIN** number on [login to view URL] see if we are the top seller on the product and if we are not flag this up so we can see who is and why. The **ASIN** number is unquie to every different product card. we would like the findings in a excel or csv so it is easy to manage and be able to increase the number of products to look up we currently have around 350.
