Baking an animated curve

Hello everybody, I’ve a question, I have a problem similar to the attached file, the resume is I want to upload to sketchfab, but that platform has no support for curves, so what I need is to bake the curve in to a mesh with shape keys or something to be able to upload it to sketchfab.

BTW the file ends with “o” for a personal joke.
