Hey,
I can write a script that will go through the images (in a directory may be) and then based on the spreadsheet find and replace columns, rename them as required.
I have a Mac, will create the script, test it over and send it to you along with the instructions to set it up in detail and would be available to help you in case you face any challenges.
Please drop a message to me if you would like me to work on this project for you and we may discuss the next steps.
Look forward to hear from you and thank you for considering my bid
Best Regards,
Rishi
