PLEAC-Perl
Cookbook of perl solutions to common programming problems. Many qualities.

Sam-I-Am.com Work: CSS
Made a start on a CSS section to house some of my work and point at the great work being done by others. Right now there's the commented backslash hack to isolate and target rules for macIE5, and the overflow:auto partial solution I have that addresses some of the problems seen in that same browser.

blog of francois
covering some interesting web-development topics. I plan on going back into the archives, as well as keeping an eye on this page.

Perl - Excel FAQ
and this example: Spreadsheet::WriteExcel

And there's a XML::SAXDriver::Excel, for transforming Excel to XML.

or there's the win32 OLE route

Perl2Exe
this is a command line utility for converting perl scripts to executable files (.exe), which can then be run without a perl install. I'm looking at this as a way of making droplets to perform simples tasks on the files/folders you drop on them. There's a shareware version (flashes a command prompt with a message each time your .exe is run) or lite & pro commercial versions.

ascii.com - File Conversion Software
Includes a word2html product that might be worth a spin (demo avail, ~$170 single seat)

Terry Morse's Myrmidon
I keep running into and it still looks like one of the best tools out there. Mac-based, installs as a print driver, so you can convert to html from any application that has a print function. Need to check it out against some sample Word docs, but the setup options and a quick test against a simpletext doc look promising. Still wouldn't hurt to push that output through Tidy or similar, but it looks clean.
And it's apparently now free. My kind of price...

RTF2HTML (EasyByte Software Ltd)
COMponent (not MS Office dependant) that will output fragments or whole html pages.

Yahoo!... WWW > HTML Converters
