Updating to provide a bit more info so that users don't have to dig through 2300+ pages of documentation just to find the useful/relevant info.

And mentioned above 'twice-check-to-dispose-everything-magic' is one of that everyday pain. But yeah, it works, and most of the time it's enough. | |

The support for formatting your spreadsheet is abysmal, which is arguably the reason for generating an .xls file and not just a flat .csv file. For example, have you tried outputting more than 911 characters in a cell, or have you tried setting the width of merged cells in a consistent manner? I have, and I can't tell you how much I hate this crap now... Do yourself a favor and go with one of the free libraries mentioned on this discussion. | |

This is argueably OK for attended applications/ workstations, but for servers is not recommended (MS has a KB stating this). For our server, we just reboot it nightly. Again, that works OK. | |
