I have the same phenomenon here with 3.0
It seems POI is not yet fully like the real Excel file format, so it
saves unnecessary information or something like that.

Hi,
I am using POI to modify an excel sheet. But somehow the file size
increases a lot even if I don't modify anything, and just save it.
When I open that saved excel sheet in Microsoft Excel, and save it, the
file size is again decreased. I am using poi version 2.5.
My code is as follows
POIFSFileSystem fs = *new* POIFSFileSystem(*new*
BufferedInputStream(is));
HSSFWorkbook wb = *new* HSSFWorkbook(fs);
fos = *new* FileOutputStream(filename);
wb.write(fos);
Thanks,
Niharika
