G-Code Viewer & Converter

G-Code Viewer & Converter is a practical utility for people who need to inspect CNC files or shift them between G-code formats. By our assessment, its real value is in the name itself: it promises two concrete jobs, viewing and conversion, and that is exactly the sort of narrow tool machinists, hobby CNC users, and shop techs usually reach for. The upside is clarity: you are not digging through a full CAD suite just to check a toolpath or reformat a file. The trade-off is obvious too, because this kind of app lives at the edges of the workflow and will not replace proper CAM software or controller-side checks. In use, that usually means quick lookups, small fixes, and a lot of plain file handling rather than anything glamorous. Astrina places it under Productivity, which fits a utility like this better than any grander category. It is most sensible when the job is to look at G-code and move it on, not to design the part behind it.
