Lang file generator for Minecraft

A language file holds the names the game shows. Use it to rename items, blocks and mobs with a resource pack, or to name the things your own mod or data pack adds. Fill in the table and download the file or a ready pack.

Namespace Language Pack for Minecraft

Namespace: minecraft to rename things of the game itself, or your mod id / data pack namespace for your own things.

Kind	Id	Name shown in the game	Key

Paste a list of ids

One id per line. A name is made from each id (ruby_sword becomes Ruby Sword); write ruby_sword = Blade of Rubies to set it yourself.

Kind

Add to a lang file you already have

Paste the file here. Its lines are kept; your rows are added, and a row with the same key replaces the old line.

Sort the keys A to Z Same file for more languages

en_us.json

Where the file goes

Resource pack: assets/<namespace>/lang/en_us.json. The zip from here has the file in that place and a pack.mcmeta, so it can go straight into the resource packs folder. Do not unzip it.
Your mod (Fabric, NeoForge, Forge): src/main/resources/assets/<mod id>/lang/en_us.json. Download the file alone.
Server: names from a lang file are shown by the player's game, so players need the resource pack. Put the zip as the server resource pack.

Good to know

A file changes only the names you list. Everything else keeps its normal name.
The file works for one language. A player who plays in British English or Spanish does not read en_us.json: add the codes of the other languages (en_gb, es_es, de_de, pt_br, fr_fr ...) to get the same file for them. For a mod, the game falls back to en_us when a language has no file.
A block and the item you hold of that block share one name: use the kind Block for both.
Ids are the names from commands: /give @s diamond_sword means the id diamond_sword. Small letters, digits and underscores only.
Renamed items keep working everywhere: recipes, commands and plugins use the id, not the name.
This is the JSON form, used since Minecraft 1.13. Versions before that used .lang files with other keys.
