    My aternos server is really laggy so I was going to switch it from fabric to spigot to get some plugins to help but it says that it will delete the current world so I downloaded it but before i switch it and then upload the world I wanted to know if all playerdata transfers with the world

    It should, but we cannot guarantee anything. Downloading and re-uploading is a hacky way to get around systems that are there for good reasons. Forge/Fabric worlds are not compatible with Spigot or Paper. (Choose Paper if you insist on switching to a plugin server, it outperforms Spigot and Vanilla by a lot)
