NBT Tags for Villager in Minecraft (Java Edition 1.16/1.17/1.18/1.19/1.20)

name (The name of the profession. There are 14 different professions to choose from and each profession has different clothing.)

Example for a Farmer
{VillagerData:{Profession:farmer}}

number (The profession level of the villager. The higher the level, the better the trades the villager can offer. If you enter a number that is higher than 5, the villager will not have any traders to offer. See villager trades to learn about the different trades based on profession and level.)

1 (Novice)
2 (Apprentice)
3 (Journeyman)
4 (Expert)
5 (Master)

TIP: A villager that is a novice will not immediately select a profession and may even switch profession. If you want the villager to hold its profession, you must spawn the villager with at least a level of "Apprentice".

Example for a Farmer that is an Apprentice
{VillagerData:{profession:farmer,level:2}}

biome (The name of the biome that the villager is associated with. The biome determines the clothes that the villager wears which means that a Farmer from the Plains biome will look different than a Farmer from the Taiga biome.)

TIP: If you spawn a villager in a different biome than their own, they will seek out the biome they were created for. This makes it difficult to keep a villager in a different biome than its own.

Example for a Farmer that is an Apprentice from the Jungle biome
{VillagerData:{profession:farmer,level:2,type:jungle}}

Lists the custom trades for the villager. It uses a combination of the following tags:

"buy" is the first item to buy

"buyB" is optional and is the second item to buy

"sell" is the item that is sold by the villager

"id" is the Minecraft ID for the item

"Count" is the number of items

"maxUses" is the number of times that the trade can be done before it is unavailable

"xp" is the amount of experience earned by a player for performing the trade

"rewardExp" determines whether the player is rewarded with xp (the amount of experience set in the "xp" tag) after completing the trade

"uses" is the number of time this trade has been completed

"specialPrice" is a special price adjustment that is applied to the price of the first buy item in a trade when the Villager Trade Menu is opened for the first time (it then disappears and is not available for the 2nd, 3rd, 4th, etc time you access the Villager Trade menu. It is one time only!) Use a negative value to reduce the price of the first buy item or a positive value to increase the price of the first buy item. (NOTE: The game will not allow the adjusted price of the first buy item to be lower than 1 or exceed the stack size of the item.)

"priceMultiplier" is the price multiplier that is applied to the first buy item in a trade. The villager can increase the price of the first buy item (not the buyB item) in the trade if the "priceMultiplier" and the "demand" values are positive. (NOTE: The new adjusted price can not exceed the stack size of the item.)
Here is the formula for the price increase:

Price increase = "priceMultiplier" x "demand" x "price"

"demand" is an integer value that determines the demand for this trade which is used to adjust the price of the first buy item automatically by the villager. A negative value indicates negative demand for this trade and that players have been trading other items with the villager. A positive value indicates positive demand for this trade and that players have been completing this trade more (relative to the other trades offered by the villager). A positive "demand" value in combination with a positive "priceMultiplier" can cause the villager to increase the price of the first buy item in the trade (see formula in the "priceMultiplier" section).
