Prevent Excel From Saving the Pivot Cache

Pivot Cache in Excel serves as a temporary storage for data used in pivot tables. While it enhances performance and aids in more efficient pivot table work, it can enlarge your file size as Excel stores this data within the file.

If your Excel file includes a pivot table, follow these steps to prevent Excel from storing the pivot cache in the file:

1. Open your Excel spreadsheet.
2. Select any cell within your pivot table and navigate to the PivotTable Analyze tab.
3. Click the Options button.
4. In the PivotTable Options window, go to the Data tab.
5. Uncheck the "Save source data with file" box and check the "Refresh data when opening the file" box.
6. Confirm by clicking OK.

After you've finished the mentioned steps, Excel will no longer save the pivot cache in your file, which will effectively decrease its size.
