So you will have smaller file size without any functional compromise. The Cache will be smaller than the size occupied by the original data. If the source data is static and never needs to be appended (snapshot reports), then delete the original data immediately after Pivot Table is created. Do you append the data often or is this a one time- snapshot data. If the source data is within the pivot table workbook… So that you can work with the pivot table even when offline. But is still applicable 20 years later! Actionįinally, we can have some best practices. I found this in a very old Microsoft Knowledge Base article. This is best illustrated in this nice table. Now when you save the file pivot table will not increase the file size. Go to Data tab and clear the checkbox Save source data with file. Right click in the Pivot Table and choose Pivot Table Options The answer is – Pivot Table will always work on the cache.īut for your file size optimization, Excel does allow you to control whether the cache is SAVED or not saved with the file. Just delete it.īut how do you delete the pivot table cache?

Therefore, for our convenience – to allow us to work offline – Pivot Table creates the cache. In this case, if you are not connected to the database then changing the pivot table will not be possible because there is no data. Inside the Excel file we just have the pivot table. If the data comes from external database or connection, then the scene is different. If you right click in the pivot and choose refresh, you will get an error saying that the data was not available. But the pivot table cache is still alive.
Common sense says that this should not work because the data was removed. Now try adding more fields to the pivot table. Now delete the sheet containing the raw data. Create a pivot table and create some report. If the raw data is right there in the same workbook, there is absolutely no practical benefit of keeping a copy of it inside the Pivot Table. So is this a feature or a bug? It’s a feature! So if you have multiple such pivot tables in the same file, the size can grow dramatically. To complicate matters further, if you go to the original raw data worksheet every time you create a new Pivot Table, it is creating a fresh, new cache for itself.
So the file size may not double but it will definitely increase. Of course the cache does not occupy exactly the same amount of the space occupied by the worksheet raw data. The file size increases and loading / saving time also increases. Before we go into WHY it creates it, just understand the impact. In either case, Pivot Table automatically creates a copy of the ENTIRE DATA. When you create a Pivot Table, there is raw data either in the same workbook or it is connected to some external source. Read more to understand when to use and when NOT to use this feature. That solves the file size inflation problem. Right click inside pivot, Pivot Table options, Data tab, clear the checkbox Save source data with file. You can ask Excel NOT to save the copy of the data and save on file size.
This increases the file size and also slows down the open / close operations. Pivot Table creates a copy of the source data and saves it in the file. It relates to files containing one or more Pivot Tables. Although there are many reasons for large Excel files, one of the reasons is easier to manage and it is largely unknown. During the discussion, one of the problems we discussed was large Excel files. Today I was conducting an efficiency optimization session for Risk Management team of a global bank.
