Summary  
This chapter introduces building parameterized models for scenario and what-if analysis, automating the generation of multi-scenario forecasts, and refining AI-assisted code.  

General domain of usage  
Business forecasting


In this section, you move from analyzing past data to predicting future outcomes.

You work with a new dataset and use Copilot to build models that simulate different scenarios.

## What You Will Learn in This Section
- You create an assumptions model that lets you test how changes affect your results;
- You build a price matrix to evaluate multiple scenarios at once instead of testing values manually;
- You generate forecasts based on different conditions and compare how they impact growth and revenue;
- You use Copilot to assist with complex tasks and learn how to correct its mistakes when needed;
- You create a final summary that presents your findings in a clear and structured way.



Discover how to use Excel with Copilot to solve real business problems. Explore practical workflows that turn messy data into structured, reliable systems. Learn how to build models, automate calculations, and generate insights without memorizing formulas. Understand how to guide Copilot, validate its output, and keep full control over your logic.

Explore the core setup and habits for working with Copilot in Excel. You configure your environment, learn how to write clear prompts, and apply safe workflows before using Copilot on real data. You focus on testing, verifying results, and protecting your files. These skills help you avoid mistakes and use Copilot with confidence further.

Focus on turning messy, inconsistent datasets into clean and usable data. You standardize headers, split combined fields, fix mixed formats, and remove duplicates using Copilot. Consider real-world scenarios and apply structured workflows to clean data safely.

Discover using Copilot to work with clean data and turn it into insights. You extract values, connect multiple datasets, handle errors, and build dynamic summaries. Learn to describe tasks in plain language while Copilot generates and applies the formulas.

Learn how to present data in a clear and interactive way. Create PivotTables, add slicers, build charts, and apply conditional formatting to highlight key insights. Combine all elements into a structured dashboard and use Copilot to support analysis, formatting, and presentation. 

Build a forecasting model using assumptions, pricing scenarios, and 12-month projections. Test different outcomes, guide Copilot through complex logic, and turn your analysis into a clear, decision-ready recommendation.

Turn your work into a reusable, product-like spreadsheet. Clean raw data, combine multiple sources into a single system, build automated reports, and package everything into a polished template with instructions that anyone can use.
