VillEdit is a Datapack which allows you to create and edit your own custom villagers. You can edit the trades, profession, biome, level and even the name with a fancy menu in no time. At the end, you will get a spawn egg to spawn your custom villager anywhere in the world.
Place down a chest, and then use a villager spawn egg on top of it (sneak and right click the top). This will spawn a Villager Editor. Right click the barrel to open the menu.
To use the editor, simply open the barrel and click the buttons. Each button will explain what it does when you hover over it. There are 5 appearance options:
To add a trade, click the green "Add Trade" button. This opens a new menu where you can create the trades by putting items in the UI. You need at least one input item, and an output item, for it to work. You can also toggle whether you want the trade to reward any XP to the player.
To remove trades, you can click the redstone to remove the last trade you added. You can also click on the redstone block twice to reset and remove all the trades.
Once you’re done, open the editor and press Save. This will give you the spawn egg to spawn your custom villager. You can use it wherever and whenever you want, but make sure to keep the egg safe. The spawn egg will work even if the datapack is uninstalled. The spawn egg will display the villager's data in the lore of the item (hover over it in the inventory)
To remove the editor, just break it.

Create custom villagers with the VillEdit datapack! This is an easy custom villager creator which works without mods.
