It would be a great idea!

This is a great idea. Excel in particular is a very useful skill, and a great skill to have in today's competitive job market.

Hi! Microsoft Office lessons are a good idea, and I hope something along these lines is possible in the future, especially given Khan Academy and Microsoft's recent partnership for AI.

A similar course for Google Workspace (Docs, Slides, Sheets) could be offered, I think, and in the case of both Google and Office, I suppose there are official how-tos and videos. Repurposing them into actionable KA-style lessons should be possible - what if AI is used to accelerate this lesson-creation process? (Other core subjects can - and should - remain human-taught in the courses, while Khanmigo offers Socratic tutoring and teaching assistantship.)
