Is there an RBXM parser and creator in Client Javascript?

I know, very specific And I could have just searched up the answers
Well, the problem is I have, it’s just that none of them really fit my requirements

For example…


Exactly what I need!
Except there is no RBXM saving functionality
And it’s outdated


Literally perfect, the one I am looking for!
Oh well, it’s in TypeScript
And it’s Outdated as well
And it’s for server side


Not outdated,
But it’s in Rust Sooo


Maybe my request is too specific and Nobody has made it yet
Or maybe I’m just not looking hard enough? (Which I doubt because I’ve been looking for days)

Honestly At this point I might as well just make my own (But it would probably be really unoptimized and not as clean)

Help and Feedback would be appreciated Thanks

Plsssssssssssssss bro I need this :sob: :pray:

What is the use case here?

RBXM editor for my Chrome extension

Ok I made the decoder but now I need to make Encoder :pray:
