Data consolidation in Excel is a powerful feature that allows you to combine data from multiple ranges, worksheets, or workbooks into a single summary. This is particularly useful for creating reports or summaries from data that is spread across different locations. In this section, we will cover the following topics:

1. Understanding Data Consolidation
2. Consolidating Data by Position
3. Consolidating Data by Category
4. Practical Examples
5. Exercises

Data consolidation can be done in two main ways:

• By Position: This method consolidates data based on the position of the data in the source ranges.
• By Category: This method consolidates data based on the labels in the source ranges.

• Source Range: The range of cells that contain the data you want to consolidate.
• Destination Range: The range of cells where the consolidated data will be placed.
• Function: The type of calculation you want to perform on the data (e.g., SUM, AVERAGE).

When consolidating data by position, Excel combines data from multiple ranges based on their position in the source ranges.

1. Prepare Your Data: Ensure that the data ranges you want to consolidate are organized in the same layout.
2. Select the Destination Range: Click on the cell where you want the consolidated data to appear.
3. Open the Consolidate Dialog Box:
   • Go to the Data tab.
   • Click on Consolidate in the Data Tools group.
4. Choose the Function: Select the function you want to use for consolidation (e.g., SUM).
5. Add Source Ranges:
   • Click Add to include each source range.
   • Repeat for all ranges you want to consolidate.
6. Check Options:
   • If your data includes labels, check the appropriate boxes (Top row, Left column).
7. Click OK: Excel will consolidate the data and display it in the destination range.

When consolidating data by category, Excel combines data based on the labels in the source ranges.

1. Prepare Your Data: Ensure that the data ranges you want to consolidate have consistent labels.
2. Select the Destination Range: Click on the cell where you want the consolidated data to appear.
3. Open the Consolidate Dialog Box:
   • Go to the Data tab.
   • Click on Consolidate in the Data Tools group.
4. Choose the Function: Select the function you want to use for consolidation (e.g., SUM).
5. Add Source Ranges:
   • Click Add to include each source range.
   • Repeat for all ranges you want to consolidate.
6. Check Options:
   • Ensure that the Top row and Left column options are checked if your data includes labels.
7. Click OK: Excel will consolidate the data and display it in the destination range.
