As shown in the following figure, the same Excel workbook is saved in the. xlsx format and the. xls format, and the first picture shows the. xlsx format, the size is 29.3K, and the second picture shows the old. xls format, which is 54.5K, and can be found, compressed by nearly half:

You can see that although the PivotTable report is missing, but the original data is still intact, you just need to take a moment to redo the PivotTable report without the heavy cost of gathering every raw data.
