Hi,

I have large spreadsheet with about 10 or so pivot tables from attached
data.
I run new data and replace the attached data with it every week. When
I update the pivots using the wizard it updates but increases the size
of the worksheet regardless of the size of the data. By the end of the
year the worksheet is over 100 megabytes which is much larger than the
dataset. I'm using Excel 2002. It seems that it is keeping the
original data reference. How do I deal with this without creating new
pivot tables every week?

Thanks
Jim
