Certain aspects of Pixelmon, such as species, NPCs, drops and structures can be edited through JSON files. These files can be accessed by using a program such as Winrar or 7-Zip to open the Pixelmon mod JAR file, and must be applied using a Datapack. JSON files can be edited with any plain text editor.

External JSON files should be edited carefully, as bad edits can potentially result in unexpected behavior from Pixelmon. Certain tools (such as JSONLint) can be used to verify that files are formatted correctly. After editing JSON files in an existing datapack, they will need to be reloaded in order for the changes to take effect. It is advised to restart your client or server to ensure all files are applied correctly.

The following types of files can currently be edited via a datapack:

File type	Description
Advancements	Governs advancements obtained from doing certain actions. These use the Minecraft advancement JSON format.

Please note: When Pixelmon is updated, internal copies of the above files may change but external will not. If you are using a datapack, keep a close eye on the changelogs and refresh or update files where necessary. Outdated files may cause issues, or contain bugs that have since been fixed.
