After spending time transforming data—removing duplicates, changing data types, splitting columns, or merging tables—you need to decide how to bring the cleaned data back into Excel or Power BI. This is where the Close section comes into play.

The Query section is located in the Home Tab of the Power Query Editor. While it may look simple at first, it actually provides important functions for managing queries efficiently. Instead of just focusing on data transformations, you also need to think about how your queries are structured.

Working with data often means dealing with many unnecessary or messy columns. When importing raw data from CSV files, databases, or online sources, it’s common to get extra columns that you don’t actually need in your analysis. This is where the Manage Columns section in the Home Tab of Power Query becomes extremely useful.
