I was naughty and cross-posted a question about this over at http://www.dailydoseofexcel.com/archives/2004/11/26/creating-a-simple-pivot-table/#comment-48929 (not because you're not the font of all excel knowledge, mind! Dick thought the same thing, although I've just commented that there’s still some stuff puzzling about all this to me…check this out: On my home pc, using excel 2007 if I create 3 complete rows of =rand() then convert them to values, then: 1: when I save the workbook, I get a file size of 50 MB. 2. If I then create a pivot table on a second sheet from this data, but don’t explode it (i.e. don’t put anything in the data or column/row areas) I get 83.6 MB for pivot and data. So it seems the pivot alone adds 34 MB. 3. If I then explode the pivot table (i.e. put all three columns in the row area) so that the pivot resembles the original data source, I get 163 MB for pivot and data, which is quite some increase. I’d expect to actually see 50 MB (raw data) plus 34 MB (Pivot Cache) plus perhaps another 50 MB MAX for the extra resource required to store the cell formatting info for the range used by the exploded pivot. So the most I’d expect this to take up would be 134 MB, but it runs to 163 MB. 4. If I delete the raw data on Sheet 1, the file size drops 50 MB to 113 MB for the exploded pivot only, as you’d expect. 5. If I drag the three columns out of the pivot, then I get 52 MB for the unexploded pivot - which is almost the same file size as for the data alone. (Note I deleted all cells below and to the right of the pivot in order to try to make sure excel’s used range was limited to the pivot only. Not sure that this worked, given this high file size) So my pivot only seems to have grown from a 34 MB footprint when created to 52 MB just because I exploded it then contracted it. 6. If I reopen the file from (2), delete the data, and save the unexploded pivot, I get a file size of 34 MB…which was what I was expecting in step 5. It seems very odd that if you expand a pivot table out, then contract it, the file size doesn’t decrease accordingly. Maybe this means that if you’re playing around with a pivot that at some time you’ve exploded, then you might want to recreate your final product from scratch to cut down on some file size.

In a pivot cache, only the raw text needs to be stored. In a spreadsheet, you have formatting which can take up space. Jeff: The difference is formatting.

Regarding your comment "The increase in file size depends on the size of the original data source that is being duplicated to create the pivot Cache." do you know exactly how? Recently I've created a couple of pivot tables and noticed that their file sizes are much LESS than a spreadsheet containing just the raw data. For instance, if I create 3 complete rows of =randbetween(0,10000) in excel 2007, then here's the resulting file size from those 3.14 million cells: raw data only 26.4 MB Pivot table only 12.6 MB Pivot table and data 39.1 MB This really surprises me.

Excel will truncate the contents of the cached version to 255 characters. I don't know if this is the case with newer versions of Excel.

I would be interested in clear the pivot table cache before a pivot table refresh, that way, I would be assured that the data received would be in datasource order, especially if using 'none' as your pivot field sort order. I am trying to avoid using the sort option, as it sometimes interferes with the grouping option (causes it to sort in correctly). Any suggestions on clearing the pivot table cache? Thanks in advance.

You very well could have only one pivot table named PivotTable2. In other words, the name field has nothing to do with the number of PivotTables that actually exist.

The sourse of data for each of these pivot tables is the same table in MC Access. Here comes the qestion, how can I avoid duplication?? Thank You.
