When people need this
Photogrammetry output from Meshroom, RealityCapture or a handheld scanner that has to reach Blender, Maya or a renderer. Also the starting point when a scan needs UV unwrapping or retopology.
PLY to OBJ converter
PLY is what a scanner hands you: raw geometry with colour stored on each vertex and no material to speak of. OBJ is what editors expect. This is the usual first step after a scan, before anything can be modelled on top of it.

Per-vertex colour does not survive. OBJ keeps colour in a material and a texture, not on vertices, so the scan arrives as plain geometry.
