Using the SPS tools in Gwyddion will not be convenient if you have a spectrum in each pixel because, well, they are intended for SPS. But it might worth a try as implementing full 3D data support would be a major change. I don't have any JPK format specification (the import module was mostly written by Sven Neumann when he was working in JPK), can you provide it?
