Expert Only: Create Shopify CSV files from different excel datasheet and template

Hi, We have an inventory of 700 products in excel file split in many sheets. - For some sheet ( about 600 products ), you will need to scrap the image link on a specific website ( only the images link, we already have all other data ) We need a shopify expert to build the CSV ready-to-upload file from this data. - We have a template to use for the description. All specs must be integrate. * You must use different template associate to a specific sheets but the main goal is the same: Create the shopify csv file. You also will have to link many products data together before to create the csv file. Many product name have the same sku. The goal is to link them and create 1 product in the csv file. By example, a battery may work for many different device. We work with excel. If the description lenght is too large, this may required to find an alternative for the longer's one. For this products, you may have to find a solution to avoid to block the project ( ie: manually upload, direct upload to shopify, other software, etc... ) Only apply if you know to create shopify csv file and have expert skills in data manipulation.
