nbtedit is a lightweight NBT editor. Its main use is editing Minecraft save data.
While for now it only supports editing level.dat files, it is planned to support other NBT files.
Caution
This project is in alpha state. While most of basic functionality works, there are many missing features and potential issues.
Make sure to backup saves before editing. I am not responsible for potential data loss.
There are available Windows and Linux versions of nbtedit. Go to Releases section and download version for appropriate operating system. Note that these are not installers, but ready to run versions (there might be required additional dependencies, especially on Unix systems).
Note
macOS version is not available to download. It is still possible to build one by themself.
If you do not have Rust installed yet, grab it from Rust page.
After you have downloaded the source code, open terminal, cd into source code directory, and run
