Conversion of jnb files to spw file format

It seems that .jnb and .spw files are used by SigmaPlot graphing software, so some sort of conversion or data transfer is likely. Considering the support for SigmaPlot's format is pretty limited in 3rd party programs, you will have to use the original tool only to achieve jnb to spw conversion.
