Timeless Time & Expense can import project hierarchies using the Tools | Projects menu item.  Timeless Time & Expense comes with an interface for Microsoft Project 98/2000/2002/2003.

This add-in allows you to import a task hierarchy from a Comma Delimited File.  This can be used to move hierarchies between single user versions of TT&E or even to move from the single-user to the multi-user version.  It will also update a comma delimited file with time and expense information. 

After downloading and installing, please see the new help file under the Timeless Time & Expense program group for file structure details.

This add-in requires a registered version of Timeless Time & Expense.
