Amazon scraper

I want to set up a programme (Windows XP compatible). It will import an excel spread sheet containing an asin or barcode (ean upc) number. And our internal Tag. Field 1 will be the ASIN Field 2 will be UPC OR EAN Field 3 will be our tag If Field 1 is filled it will go to [login to view URL] (german site) and scrape from their listings and insert in. Field 4 will be (Amazon German Title ) (heading = Title) Field 5 will be (Von Manufacturer) (heading = Manufacturer) Field 6 will be for (**Modellnummer:**) (heading = part number) If field 2 is filled it will also add: Field 7 (German Asin) So if you input on german site as an example B000BC8VSU (an asin) it will fill in: Field 4 Lexmark C530, C530dn R?ckgabe-Tonerkassette Gelb, 1.500Seiten Field 5 Lexmark Field 6 C5220YS BUT if I input on german site as an example 0734646039482 (UPC) it will fill in: also Field 7 B000BC8VSU If you search that UPC you in fact will get several results in which case it will need to insert a new row and repeat the field for the extra results. It will then go to [login to view URL] and scrape the same information. Filed 8 9 10 and if required 11 (with multiple results being possible)
