Did anyone find a plugin that can read Extended Collections?

I’m trying to find a plugin for exporting variables. I was very happy with Variables2css because it has alias fallbacks. But it won’t run at all if the file has extended collections. I then went down a wormhole trying to find another plugin, but all of the ones I tried (i must have tried like 6 of them) return “0 variables” or otherwise empty for the extended collections. 

I wanted to use Figma’s native export but it only outputs JSON, not CSS.
