The NCL file format is documented here. You can use the VIs found at [Program Files]\LabVIEW\examples\nixnet\logfile.llb. The XNET Open Logfile.vi in that .llb is a good place to start.
DIAdem can open the file if you convert it to TDMS. The LabVIEW VI mentioned in my post above is as close to an application as we get. It uses an API to read the file and should give you the ability to work with the files grammatically. Do you need a LabVIEW stand alone executable so you can add it to your VeriStand Tools menu? If so, you could use the VI mentioned above and LabVIEW to make an executable. Someone may have been working on something similar here.
