How do I import a .zip minecraft map into Minecraft?

First of all, you need to make sure that this .zip file isn’t a Minecraft Java world. This is because Education Edition runs on Minecraft Bedrock 1.14. If you’re sure it isn’t a Java world, just rename the file extension (the .zip) to “.mcworld”. Be sure not to install a map from 1.16+ or else it won’t work due to it coming from a later version.
