[Haskell-cafe] COM and Haskell

[Tim Docker]

There are also equivalent libraries (for producing xls files without
excel) for

python: http://sourceforge.net/projects/pyexcelerator
http://sourceforge.net/projects/pyxlwriter/
perl:   http://search.cpan.org/dist/Spreadsheet-WriteExcel/

so you don't have to use java...

I hate to recommend Java to Haskellers, but there is a project named Poi
at Apache's Jakarta site[1] that will allow you to (with some Java
programming) read, write, and manipulate Excel files directly. You don't
have to COM to Excel, you don't even need Excel installed! Nice for
producing spreadsheets for download from a web-based app on the fly.

It is complete enough to do formatting, formulas, and such, but you can
see the ugly internals of the Microsoft file formats bleeding out, or at
least that was true 4 years ago.

Maybe it would be a nice project to create a Haskell version of Poi.
