NBTExplorer is a powerful, easy-to-use editor that allows you to view and edit any attribute of your Minecraft world, including player inventories, enabling and disabling hardcore mode, and much more! It’s used for editing any file that uses the NBT file format, which is what Minecraft uses for most of its world data.

#How to Use NBTExplorer to Modify Your Server World

Now that you’ve downloaded NBTExplorer and completed the setup process, you’re ready to modify any value you’d like in your world, such as changing your world to hardcore mode, which this guide will cover! You can do this by following these instructions.

  1. Access your Control Panel and Shut Down your server.

  1. Backup your world before making any changes. You can manually back up your Minecraft server by following our guide here.

#More on NBT Editing

Now that you understand the basics, you may be interested in what else can be modified. With NBTExplorer, you can add or modify existing entity data inside specific regions in your world. It’s recommended to modify an existing single-player world as practice or to create a copy of your server before making any changes.

If you’re interested in using a web-based NBT tool instead of installing one, you can find a popular alternative here.
