Power Query Essentials: Combining and Restructuring Data

This Power Query training helps you stop wrestling with messy spreadsheets and start building clean, repeatable data workflows. Power Query Essentials: Combining and Restructuring Data is built for Excel and Power BI users who need to prepare data quickly, without relying on complex formulas or manual copy-paste.

Many teams struggle with data scattered across regional files, quarterly reports split into separate columns, and records duplicated across systems. These layouts might look neat, but they block basic reporting tasks such as trend charts, filtering, and dashboard refreshes. This course identifies exactly where these structures break down.

You then learn the practical tools to fix them: appending to stack tables across multiple months or regions, merging to pull in additional fields such as customer or product data, and using conditional columns to build simple decision logic. Grouping speeds up large reports by pre-calculating summaries, and unpivoting converts wide, column-heavy tables into the long format that Power BI and Excel PivotTables need.

Hands-on examples run throughout the training, from consolidating monthly sales files and joining transaction records with customer details, to auditing two systems and flagging changed or missing values during reconciliation.

By the end of this course, you will know how to transform raw, scattered data into report-ready tables and keep them updated automatically. It suits data analysts, financial reporting teams, and any Excel or Power BI user who wants faster, more reliable data preparation skills.

In this course, you will learn how to:

Stack Power Query tables using append transformations.
Consolidate multiple Excel files into one Power Query table.
Join datasets in Power Query with merge queries.
Compare data with full outer merge joins in Power Query.
Reshape wide Power Query data using unpivot columns.
