Copy + Paste text from old webshop to new

In a week we are going to move our webshop to a new platform and for this we need someone that can copy information from the old webshop to the new one. It is productdescriptions, editing attributs for all the products and price the attributes and products in the right way. We also need all pictures of each product matched from the old webshop to the new one. The old webshop is live on the internet so there you just will copy the text into the new webshops backend witch is Prestashop based. Its not hard but if you have skills from Prestashop it will be a plus. It is about 180 products and each products has two diffrent attributes to be set.
