MS Excel is the most common format exchanged between teams to quickly look at a table, in this case Project PLAN view.
MS Excel is more universal and most likely everyone has a copy, MS Project is not a software everyone has.
An Export to Excel option similar to Export to MS Project should be made available. Again the Export to Excel element is available from many pages in Windchill and having it in the Windchill PLAN page will add a lot of value.
