# command_extractor<\/p>\n
***Command Extractor*** is a Minecraft mod that extracts available in-game commands to a JSON file, using the same mechanism as the Minecraft built-in data generator.<\/p>\n
This mod is useful if you are a Minecraft datapack developer\/programmer working in an environment with modded or user-defined commands. Several Minecraft datapack and command-related tools, such as MCDatapacker (I made it), Spyglass and Beet’s mecha, accept a user-defined `commands.json` file. That JSON file defines structures and arguments of various Minecraft commands. You can utilize the file exported by Command Extractor to make these tools aware of these custom commands.<\/p>\n
This mod requires Architectury API mod to be installed.<\/p>\n
_Command Extractor_ currently supports Minecraft 1.20.1, 1.20.4 and 1.21.1, tested on Forge, NeoForge*, Quilt*, and Fabric. Use older versions of the mod for Minecraft 1.19.2 and 1.19.4. Starting from Minecraft 1.21.1, the mod is only available on Fabric and NeoForge. Note that sometimes a version of the mod may work on other patch versions of Minecraft, but I don’t test all combinations. For example, the mod version for Fabric 1.21.1 also runs on Fabric 1.21.5.<\/p>\n
## Usage<\/p>\n
Run `\/cmdextr` command inside the game to extract commands.<\/p>\n
The extracted JSON command tree file will be saved into `extracted\/commands.json` in the game folder.<\/p>\n
By default, the `cmdextr` command itself is not included in the output file unless `\/cmdextr all` is used. Nevertheless, the output file contains both vanilla and non-vanilla commands.<\/p>\n
## Mods incompatibilities
\nSince the mod uses the built-in logic to export data, it can’t gracefully ignore problematic commands. Therefore, this mod may not play well with some other mods.<\/p>\n
In my tests, the following mods don’t work with Command Extractor:
