Optimization and functional improvement of the Excel spreadsheet

Working with Sergey is always a pleasure! He not only completes tasks quickly and professionally but also suggests improvements that I hadn't even considered. This time, the result exceeded my expectations — everything was done clearly, conveniently, and with attention to all the details.

In the future, I plan to turn to Sergey for the refinement of other tables, as I am confident in his skills and attention to detail. Thank you very much for your help and quality work!

As always, everything went great. No problems.
