Marcelo2mw/vsto_crud_products — reverse-engineered prompt

Build me a simple Excel add in for managing products, basically a small CRUD tool that feels easy for a normal office user. I want a clean panel or form where I can add a product, see the full list, update details, and delete items when needed. Include common product info like name, code or SKU, price, quantity, and maybe a short description, then show everything in a tidy grid with search and simple filters so it is easy to find things fast.

Please make the flow straightforward, with clear buttons, validation so bad or empty data is not saved, and friendly messages when something works or fails. It should feel polished enough to actually use, not just a rough demo. If the current project already has pieces started, keep and improve them instead of rewriting everything for no reason. Make it runnable from the existing solution, and look up current docs online if you need to fill in any Office specific details.
