Comparing Data Across Multiple Worksheets with PivotTables

English, Solutions

Comparing data across multiple worksheets using PivotTables in Excel can be streamlined by combining the data into a single PivotTable, even if the data is initially split across different worksheets. Here’s how you can effectively manage this:

Method 1: Consolidate Data into a Single Worksheet

Copy Data into One Worksheet:

Gather data from each worksheet.
Ensure that all datasets have the same structure (same columns).
Copy data from each worksheet into a single worksheet, stacking them on top of each other.

Insert a PivotTable:

Select the entire dataset.
Go to the Insert tab on the Ribbon.
Click on PivotTable.
Choose whether to place your PivotTable in a new worksheet or in the existing worksheet.
Design your PivotTable to compare and analyze the data.

Method 2: Use Power Query for Consolidation

Load Data into Power Query:

Go to each worksheet and load the table into Power Query.
Go to the Data tab and select Get & Transform Data.
Use the From Table/Range option.

Append Queries:

In Power Query, use the Home tab and select Append Queries to combine all the tables.
Ensure all tables have consistent columns for successful concatenation.

Load Combined Data:

Once appended, load the resulting combined table into Excel.
Use this newly created dataset to insert a PivotTable.

Method 3: Using Excel’s Built-In Data Model (For More Advanced Users)

Add to Data Model:

Go to each worksheet.
Select your data and Insert it as a table.
When creating a PivotTable from each table, select the option to Add this data to the Data Model.

Create a PivotTable from the Data Model:

Insert a PivotTable and select Use an external data source.
Choose the Excel Data Model.

Manage Relationships:

In the PivotTable Fields pane, establish relationships between tables if they are interconnected via common fields.
Build your PivotTable to analyze data from multiple sources.

Summary

These methods allow you to effectively compare and analyze data across multiple worksheets using PivotTables by consolidating data into a single analyzable table. The Power Query method offers a repeatable process for dynamic data updates, and using the Data Model enables more complex data relationships and analysis. Choose a method based on the complexity of your data and your familiarity with Excel features.
