Hi all,

I found that in many reporting software, they also have a built-in function
to export their report in Excel format, no matter the PC have Excel installed
or not. I searched in web and found that most of the sample code is creating
the Excel COM object (Excel.Application, Excel.Workbook etc....) and then
write their contect into each cell and finally close/release all the
reference. However, is it the way those reporting software I have mentioned
before export their report into Excel format ?
If not, how they can do that ? Is it there is some API which I can call to
achieve it ?

Thanks in advance

The excel file format would be pretty difficult to create.

But you could create a comma separated value file (plain text file) in your
application.

If excel is on a pc, then the .csv extension will be owned by excel (if the user
hasn't changed it).

If you really want to try, you may want to review the posts by Tom Ogilvy in
this thread:

It seems to me that this approach would not work unless Excel is installed on the
host machine. How else does the software activate the Excel object?

He is asking if this is how "commercial" software works -- he describes how
software found on the web does it (using Automation). The answer is No -
"commercial" software writes to the Excel file spec, since as you say,
automation/COM requires Excel to be present.
