Is it possible to transfer Minecraft PE worlds to Minecraft PC?
You can try using iFunBox, a program for Windows and Mac that allows you to browse your iOS files. You can use it to browse in Minecraft PE and find your world. When you do, you can copy it to your desktop. Hope I helped!
Copy /games/com.mojang/minecraftWorlds/WorldName on Android to %AppData%\.minecraft\saves on PC
If it doesn't work you need MCEdit (download from here), import the world on MCEdit and then export it as a PC world
