...Amulet is a Minecraft world editor built from the ground up with the lessons learnt from previous editors in mind. The program works natively with the block state format introduced in 1.13 which enables editing of all world formats. Amulet is built on top of a world converter that converts all world data into a custom superset format. This means that all worlds can be modified in the same way rather than having custom logic for each world format. Amulet comes with a built-in world converter that can be used to convert any world Amulet can open into any other world Amulet can open.
