I am attempting to import publicly available shapefile data from http://gis.utah.gov/data/boundaries/zip-codes/ into Tableau for a data visualization project.
Unfortunately, the .shp file and .gdb database that are available for download include only the shape length / area for each of the Utah zip codes.
My goal is to convert these from the current NAD 1983 UTM 12N (EPSG: 26912) format into latitude / longitude coordinates that can be read into Tableau.
I am using Quantum GIS (QGIS 2.0.1) and would appreciate any and all help.

The layer is provided as a polygon so you'll need to convert the polygons to points and calculate the XYs of each point.
This should give you a point file with the vertices for each polygon and the respective calcualted X and Y values for each point in the chosen CRS.
