Packages like femgl ([GitHub - mikolalysenko/femgl: WebGL finite element viewer](https://github.com/mikolalysenko/femgl)) and GridApp ([GitHub - gridap/Gridap.jl: Grid-based approximation of partial differential equations in Julia](http://github.com/gridap/Gridap.jl)) employ finite element mesh files in JSON format. How are these files created (preferably from meshes generated using GMSH (gmsh.info)). I was not able to find an appropriate conversion tool.

Thanks! Domenico
