List create Excel datas -- 2

I need someone to export products from one woocommerce store to another. The export will go to a spreadsheet. Simple products will be turned into variable products for size only. Current variable products will be mapped to attributes because the current products are custom attributes and need to be mapped according to color and size. Any other extra fields in the spreadsheet will be removed. Then the spreadsheet will be uploaded to the new site. If you have good experience with import export and manipulating data in spreadsheets then please apply and tell me how you plan to approach this job. Thanks.
