To me, your only real hope is to save it as a schematic using worldedit and find a schematic to nbt converter. There is a PHP script if you want (https://github.com/svilex/Minecraft-StructureConverter). I found it online but it may not be what you are looking for. If that doesn't work, then just google "schematic to nbt converter" and you are bound to find at least something to help you.
