convert & import an excel file into GW 8 (*.ics) calendar. Is this possible?

I've been tasked with getting a fairly large excel file imported into GW calendar.  The formats (XLS, XLSX, TSV, CSV, TXT, ICAL, etc) between Outlook calendar files or Excell and GW calendar (ICS) are completely different.  ICS files appear to have an encryption.  I've tried bs_gwvcs.exe to no avail. I've tried the standard changing the extension and just trying to import the file in GW. no luck.  bs_gwvcs.exe seems like the answer, but only imports ICS files.

 While GroupWise appeared to import the extension changed file though nothing showed up in the calendar, b/c the format was not correct (obviously).  The trick I need to find is a way to convert the format from Excel to ICS and get the format changed over so that it can be successfully imported.  
Is this even possible?

thank you, I'll give this a show and let you know. I've run out of time to try it today so it may not beb until monday that I send a response, but this does look like a viable solution.

Great news, those applets could be a great plan B.  Luckily, since I'm dealing with newer software (Outlook 2010 & Groupwise 8), the programs communicated with each other splendidly.  But, I have both apps (applets) just in case...
    *  Personal Microsoft Outlook Migration applet
    * Advansys Formativ Express
Both from Advansys.

I'd say the trickiest part is getting used to MS Outlook 2010's options.

Thank you for all of your help.

it required a little learning on my part to understand the changes in MS Outlook 2010 to navigate the process.
