Data relationships in Excel allow you to connect tables based on common fields, enabling better data analysis through tools like PivotTables. This feature is especially useful when dealing with large datasets stored across multiple tables.
What Are Data Relationships?
A data relationship connects two or more tables using a common field (key).
Similar to relationships in databases, Excel allows linking tables using primary keys and foreign keys.
Commonly used in Power Pivot and PivotTables.
Why Use Relationships in Excel?
To avoid redundant data by storing it across multiple tables.
To analyze data collectively without manually combining datasets.
To create meaningful reports and insights.
Steps to Create Data Relationships
Prepare Your Tables
Each table must have a unique column (key) that links them.
Tables should be formatted as Excel Tables using Ctrl + T.
