Hello Mark Stefenelli ,
Thanks for reaching out in the Microsoft Q&A!
Copilot isn't directly designed for working with Excel files.
For Excel users, leveraging VBA can streamline your workflow. These mini-programs can compare lists, highlight price changes, and update your existing list.
If you're open to a more advanced solution, consider using Python with the Openpyxl library.
Both approaches will save you significant time and ensure your pricing remains accurate. Choose the method that best suits your needs.
