As there are some issues running AutoIt3 scripts or compiled .exe's against the Excel object model, I completely rewrote this Excel to Html converter in Java 6.
It's still called Excel2Html v2 and the version number is now 2.0.1.1, as I had to do a few improvements.
Excel2Html v2 is 99% backward compatible with the v0.x release, except for the -et command-line parameter, that is no longer supported.
Download and information is available from my DCMembers.com page.
