Current Pattern Data Entry

Hello, We need to add products to our website. The information is taken from existing websites and is pasted onto a Google Docs spreadsheet. This information is not proprietary and basically is just the name of a product, the brand and pattern/model and the retail price (MSRP). There are many, many products to add. I am not familiar with the nature of this site or how the best way to approach pricing for this would be. Am open to the best suggestions.
