The next approach that can be used to reduce the excel file size is to convert unnecessary formulas into values. Below is the list of steps that one can use to understand the methodology.

• Step 1 – Open the excel file, and select the entire worksheet or the number of columns to be converted from formulas to values.

#3 – Compress Image

The next approach is to use compress the image into an excel file to reduce the workbook size. This method is essential when we have too many images contained in the workbook or worksheet, which drives to increase the size of the excel file.

• Step 1 – Click on the image you want to compress. Then go to the “Format” tab in the ribbon area, as shown below.

This is the picture tool that appears only when the image is selected.

• Step 2 – In the “Format” tab, select “Compress Pictures.”

• Step 5 – Click on Ok and save the workbook. This will reduce the size of the overall excel file.

#4 – Deleting Pivot Cache

The following approach will help reduce the excel file size by deleting the pivot cache while creating the pivot table from the source data.

• Step 1 – Select the “Analyze” tab in the pivot table tools. This tab appears only when the pivot table in the excel file is selected.

• Step 2 – Now click on the pivot options dropdown followed by options.

• Step 3 – Next to a dialog box would appear, go to the Data tab.

• Step 4 – Now deselect the checkbox for “Save source data with the file.” This option will not create any pivot cache and enables to reduce the excel file size.

• Step 5 – Now select the Option for “Refresh data when opening the file” this will ensure that the pivot is refreshed as soon as the excel file is opened. If the option is not selected, then the pivot table needs to be refreshed manually, which would lead to generating a pivot cache.

Step 6 – Then click on the OK. This will ensure that the excel file size is reduced.

Things to Remember

• XLSB file format tends to open and save at a much faster rate. However, there are even a few things to consider where macro-enabled and query-based excel files should not be converted to XLSB as they might cause functional errors while operating as XLSB.
• Also, if the excel file size for XLSX format is 5MB to 7MB can be left as is, only if the XLSX file size zooms to double or triple digits in MBs. Then can the excel files can be considered to reduce the file size using any of the best-suited approaches.
• There are other approaches such as using the compressed zipped folder; this is done by doing right click on the excel file, go to send and then click on a compressed zipped folder. This will reduce the file size while sharing. This can also be done by selecting multiple files and then compressing the files in a zipped folder.
• Prefer pivot tables over formulas used to summarize data for generally larger data sets; this will have less impact on the file size. Also, if there is higher usage of formulas being made, then change Automatic calculation mode to Manual mode in the formula tab. This will make the file open, making changes, updating the excel file, and closing the files much faster.
