How to append queries in Power BI to combine multiple tables | Power BI tutorial

Learn how to use the Append Queries feature in Power BI to combine multiple tables into one.

🎓 What you will learn:
✅ Why Append in Power BI is appropriate for combining the tables in the example
✅ Why the tables must have the same structure
✅ The checks to be performed prior to using Append such as ensuring matching column names, column order, and data types across the queries
✅ How to Append Queries using Power Query
✅ Sense checks to be carried out in the combined table
✅ How to fix the Append if the wrong number of columns appear after the Append

This tutorial emphasises the crucial requirement that both datasets must have identical structures (same number of columns, column names, column order, and data types) for the append function to work correctly. If the tables have different columns then some data manipulation will be required before Append can be used to combine the tables.
