CSV /spreadsheet editing/link correction for 124 records

I have a spreadsheet CSV file in excel the has contains 124 records. About 80-90% of these records contain correct links to products images but the remaining 10% contains dead links that will need to be double checked and edited. I will provide a separate CSV file sheet that shows the image links that should be applied to the correct product descriptions. Once this is finished for one spreadsheet it will need to be applied to 4 other variations of the same CSV through simple copy and pasting. This should be an relatively easy project to handle for an Excel professional. I pay on time and promptly for good work. Check my feedback. Thanks, Merchant 00
