Modify Player Data

This mod allows Minecraft's data commands (/data, /execute store, etc.) to modify player data.

Alongside supporting most vanilla player NBT tags, this mod also adds the CustomData NBT tag, which can be used to store any type of NBT data on a per-player basis.

Feel free to report any bugs, or suggest new features, at the issue tracker.

Usage

Mod builds can be found here and on Modrinth.

This mod is currently available for Minecraft 1.21+1, 1.20.5+6, and 1.20.4. Releases for older versions of Minecraft are generally no longer updated, but should work fine. The Fabric API is not required. This mod is not required on clients.
