How to Downgrade Worlds via Blocktopograph

Tutorial

In order to open Worlds that have been loaded in newer versions, you have to edit "level.dat".

Step 1:

 Download and open up Blocktopograph and select the world that you want to use

Step 2: 

Swipe from the left of your screen to the right to bring up a list of things and tap on "World NBT"

Step 3: 

Look for "MinimumCompatibleClientVersion" and edit that to the corresponding Version and then save

Important:

- Blocks from newer Versions turn into Placeholder blocks that will revert back to what they were once updating (This feature did not exist before 1.16.100! All blocks will get replaced with air if you do this in 1.16.40 or lower. You can prevent this by going far away from new Blocks)

- Items from newer Versions in your Inventory, Ender Chests, or Storages like Chests and Placed Shulker boxes will get removed (You can prevent this by going far away from your Chests or by putting the items into a Shulker Box and then keeping the box in item form.)
