With all his expertise, he can definitely bring a lot to the table being a consultant or mentor to all kinds of businesses.
Regarding programming, it depends if he just wants to work or work to earn money.
If the former, he could look at OSS projects that interest him, there are so many! He could make meaningful contributions (for the project and for him)!
If the latter, he can definitely give it a go but maybe not get his hopes up too much. He could start his own startup/blog/company though which might not be a bad alternative to paid work.
Also he could look at the no-code tools which would allow him to build stuff quicker than learning to program. It would probably be a step up from Excel already and he could see if he likes it and wants to dive deeper (some contractors are specialized in building stuff on top of no-code tools)
Anyhow, good on him to want a career change at 60+, I wish him all the best!
