Excel Writer/reader

Has anyone come across a useable Excel reade/writer Class, that we could wrapp for B4Ppc...
I found one, but so far I have limited success, as I can only create a workbook, add some worksheets, delete worksheets, and not much more...
It is based on CarlosAg Excel Xml Writer library, but is has a too intricate funcionality....

I believe that being able to produce excel files, as oposed to csv, would be a biggggg plus to b4ppc....
Not just for data storing, but also for report generation etc...

There's a control in Borland's VCL, Delphi or C++ Builder. Don't know if it's any use though I'm afraid. But several of their compilers are free so it's useful to have one handy for reference. Supporting NET is a bit tedious I'm told.

Remember that the dev version of Excel is missing huge chunks of the sexier bits.

Something like this.....

This is a good stating point, but needs that Excel it-self is isntalled..
Using CarlosAg dll, we are creating a excel file from an xml format, therefore no need to have excel installed.
Also, I wnat/need to be able to do some basic formating to to cells, such as font, color, bounds, etc...
