Comment Office Doc Generation on the Server (Score 5, Informative) 259
I would like to point out another good option Joel doesn't have on his list. It's a software called OfficeWriter, from a company named SoftArtisans in Boston.
When I last checked/worked there, it was capable of generating Excel and Word docs on the server, and I believe Powerpoint was probably coming relatively soon. Creating a product that can write office documents isn't quite as impossible in terms of labor as Joel is saying.... but it's still way beyond any hobby project.
Plus, he is suggesting that you use Excel automation or the like through scripts to create documents on the server, which is a decent suggestion, if you want Excel or Word to constantly crash and lock up your server, and you enjoy rebooting them every day. If you want to do large scale document generation on a server you are going to need something like Officewriter.
