Summary  
This chapter demonstrates how to use code to analyze tabular data with an AI assistant, generate concise natural language summaries, and programmatically create new sheets with supporting charts based on specific criteria.

General domain of usage  
Financial analysis and executive reporting



In this chapter, you turn your analysis into a clear business decision.

You move from numbers and models to a structured message that someone at the executive level can understand and act on.




Start by asking Copilot to summarize your forecast.

Keep the output in chat so it doesn’t modify your sheet. This gives you a fast overview of which scenario performs best and what trade-offs exist.

Generate a Quick Summary


Next, ask Copilot to turn that summary into a professional memo.

Include clear context, a recommendation, and reasoning based on your model. Copilot can structure the content and format it into a new sheet.

Create a Decision Memo


Enhance the memo with a chart.

Copilot can generate and place a visual that supports the recommendation, making the message easier to understand.

Add Visual Support


Always review the result.

Copilot does not know your full business context, tone, or priorities unless you provide them. Adjust the wording and positioning so the message fits your audience.
