Copy price data from one excel sheet to an other

Our company is called Brok Bouwmaterialen and we sell building materials in the Netherlands and Belgium. We are going to expand our business activities with decorative paving. Our website software is Lightspeed and the new products will have to be imported into this system. We have an excel file with data about the products. This data must be put in another excel file, so that we can import the right information into Lightspeed. In total there are +/- 900 products. We are looking for someone or an organization that can realize this. We have now explained the assignment fairly broadly, more specific explanation of the assigment will follow when we find the right person/party for the job. Let us know if you're interested!
