Format get lost in excel file

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open an excel file that has formatted text using CompoundDocument.Open
2. Save it with a different name. All the format was lost

I expected that the format were kept.

The same happened when I set a bold font programmatically and then saved 
the file. Format is not taken into account

The version of the product is of 03/31/2009

Same here. I created a template file with Excel, then edit (add rows) and save. 
It lose everything but images and content. Cell size, font settings, it will 
delete everything.

This issue is still confirmed in release 55.  Create a Workbook with some 
formatting (bold, different font sizes, etc.).  Open the workbook write data to 
a cell and then save it using the ExcelLibrary.  All the original formatting is 
removed.

Even without changing anything, it removes the formatting: Example:

Create a document with formatting. Save it. Open it with a stream, 
WriteToStream. And all formatting is gone.
