In this blog post, I share a number of practical Microsoft 365 Copilot tasks in Excel that focus on real, everyday data analysis and reporting scenarios.
These examples demonstrate how Copilot can help with understanding data, creating formulas, and uncovering insights. While this post includes a selection of tasks, they are intended to get you thinking. Copilot in Excel can support many more scenarios, especially when working with larger or more complex datasets.
My goal is to provide ideas and practical prompts that you can try yourself and build upon as you explore further.
