Unfortunately, XLS file format is VERY complicated. See
http://sc.openoffice.org/excelfileformat.pdf and you will see what I mean.



However, you have free alternatives. For example, ExcelLite Free is a free
..NET component that can read / write both XLS and CSV files. You can use it
in a commercial applications; it is only limited to max 150 rows per sheet.
You can download it he

Hello, I have found a few conversion applications that I can download to
convert a CSV file to an XLS file.

Is there a specification on how to do this conversion? What did the
developers of these conversion apps use as a reference for developing
their tool?

I want to understand the requirements of building an XLS file from a
CSV file and write a simple script/app to take my query results (in csv
format) and put it into an Excel file that can be viewed using any
version of Excel.

Thanks,
Chris
