Why Power Query interface overview in Power BI? - Purpose & Use Cases

The Big Idea

The Scenario

Imagine you have a big messy spreadsheet with data from many sources. You try to clean and organize it by clicking and typing in each cell manually.

The Problem

This manual way is slow and tiring. You might make mistakes, miss steps, or forget how you cleaned the data. Every time new data comes, you repeat the same boring work.

The Solution

Power Query gives you a clear, easy interface to clean and shape data step-by-step. It remembers your steps and lets you refresh data with one click, saving time and avoiding errors.

Before vs After

✗ Before
