How to use a NBT Editor

Okay so i want to change the value of a item with a NBT editor. The value i want to change is the stack limit. The steps that i did was

  1. Placed a few stackable blocks in my inventory
  2. Found my level.dat
  3. Placed it inside THIS website
  4. Then i Players -> Inventory
  5. Found the items im holding in

But i don't know how to change the value so you can't stack any items at all!


Solution 1:

The stack limit is a property of the game. NBTEdit can only edit data that the game can handle. You can't modify the game itself with it.
