Excel spreadsheets can be easily expanded, especially when they contain a lot of data or images. While that is not always a problem, it sometimes makes it difficult for users to manage, share, and process spreadsheets effectively.

Luckily, you have a few ways to reduce Excel file size without affecting the data. Below are detailed instructions.

Delete unwanted tables

There are too many unused tables causing unnecessarily large Excel capacity. Therefore, you should start by deleting the spreadsheet that you don't need there. To do this, open the Excel file, right-click on the unwanted worksheet and select Delete .

Additionally, you might also consider removing charts, pictures, tables, and other unwanted elements.

Remove unnecessary formatting

The size of an Excel file can also increase due to excessive cell formatting, because each formatted cell takes up more space on the file. For example, cells with borders will take up more space than unformatted cells.

Therefore, you should remove any unnecessary formatting from the Excel table. To do this, use these steps:

1. Open the Excel file and select the cell you want to remove formatting from.
2. Click the Home tab at the top.
3. In the Editing group , click the Clear button and select Clear Formats from the resulting menu.

You can repeat the above steps to compress more photos if you want. Then, the overall file size will be significantly reduced.

Prevent Excel from caching Pivot

Pivot Cache in Excel can be a temporary storage location for data used in pivot tables. While that can improve performance and allow you to work with pivot tables more effectively, it increases Excel file size because it saves data to your file.

If the Excel spreadsheet contains a pivot table, follow these steps to prevent Excel from caching the pivot to the file.

1. Open the Excel spreadsheet.
2. Select any cell of the pivot table and click the PivotTable Analyze tab at the top.
3. Click the Options button .
4. In the PivotTable Options window , click the Data tab .
5. Uncheck Save source data with file and check Refresh data when opening the file .
6. Click OK to confirm.
