Microsoft Power Query recommended for Excel data cleaning

Power Query is presented as the primary tool for importing, cleaning, merging, and reshaping messy data within Microsoft Excel and Power BI. It automates repeatable ETL steps, allowing users to refresh queries without rebuilding formulas.

PivotTables are advised for fast aggregation and interactive exploration of already‑clean, table‑shaped data, while formulas remain useful for cell‑level calculations that must update instantly. The suggested workflow is to shape data with Power Query, model it if needed with Power Pivot, then analyze with PivotTables, reserving formulas for specific logic.

A beginner‑friendly course titled “Power Query Essential” teaches these capabilities, covering error removal, column splitting, table appending, and automation of routine data‑cleaning tasks without coding.
