Has anyone created an MS Project XML mapping file to be used with Excel?  I've been tasked with importing some larger existing project plans that were done in Excel.  According to the help, in order to export it from excel in a format that can be imported into ProjectLibre, I have to have a "mapping" file that will map the excel columns to the XML schema.  I took a couple of runs at it without luck.  Not really sure what I am trying to achieve with it.  As a related thought, any plans for a CSV import function that could eliminate all this run around?  Thanks for the help.
