Often find myself getting frustrated editing yaml, and it seems to be used everywhere for some reason I cannot fathom

I have an idea to write an editor plugin that will, when opening a yaml file, convert it to json (or some other less painful configuration language), then convert back on save. I don't know enough about yaml syntax to know if that's possible or if there's some quirk that makes them not completely cross compatible

Or alternatively if it exists a better CLI tool for editing yaml than just a normal text editor because I'm getting sick of pasting in a block of yaml and then having to fix the 8 indentation errors that somehow spawn from that
