How "independent" / platform-agnostic is the save format for this plugin?

[nikhilCad]

I could see the save format is json but we are base64 encoding it, is this save format custom made for this plugin only, or is it for excalidraw in general? I could see that we can export as SVG (in the intro video, even youtube links were working fine when exporting :) ) so that is great, meaning I can use it elsewhere.

Main reason for asking - I am coming from OneNote whose drawings has a pretty locked down format that I can't use anywhere else without going through some hacky stuff. In fact main reason for using Obsidian now is that is uses markdown which I can just take with me to other apps in case the company goes under.

EDIT: My question was answered at around 2:55 here https://www.youtube.com/watch?v=i-hIfY-Ecjg it is excalidraw site save format, thank you very much!!
