Hi @Mahmoud Amish Welcome to the community! Excited to hear that you're planning a course on about Excel, Word.
This community is a space for Udemy instructors (aspiring and published) to chat about course creation, marketing, management, and more, so this may not be the best place to see if someone is interested in your course.
I'd recommend using Marketplace Insights and reaching out to relevant groups on Facebook, LinkedIn, etc. to see if folks would be interested in this type of course. Best of luck!
