The export format that used to work was comma separated variable (*.csv). MS removed that feature (import csv file) from Visio, Not sure if it was as of Visio 2003 or Visio 2002. I do know that Visio 2000 works. If you can find a back-level Visio installation, you can import there and bring it forward as a .vsd file. I believe the end user license agreement for Visio allows one to use a back level version if a newer one is licensed.
Hope this helps. Please rate helpful posts.
