System Documentation

What problem does it solve?

The Power Query Coach helps users transform messy, inconsistent data into clean, analysis-ready formats using the Power Query UI. It diagnoses structural issues, visualizes the ideal data state, and guides step-by-step transformations to ensure reproducible results.

Core Features & Use Cases

  • Diagnoses common data structure problems (wide formats, multi-row headers, grouped data) and explains impact.
  • Visualizes the target long-format structure and provides an actionable transformation plan.
  • Guides UI-driven steps (fill down, unpivot/pivot, type corrections, date locale) with best practices.
  • Use cases include cleaning exported reports, preparing data for Pivot Tables or Power BI, and building repeatable ETL workflows.

Quick Start

Use Power Query to transform a messy dataset into a clean, analysis-ready table by filling down merged/blank cells, unpivoting wide data to long format, and setting proper data types with locale-aware date handling.
