NBT Studio – Edit Minecraft NBT Files & Data

NBT Studio is an NBT editor that makes it easy to customize Minecraft worlds and items. Instead of manually typing commands or digging through config files, you can open NBT data in a graphical editor and change what you need. Create custom potions with any effect, add rare enchantments to tools, build spawners with custom entities. The app has everything you need whether you’re working with Java or Bedrock.

NBT Studio started as a successor to NBTExplorer but was completely rewritten from scratch. It keeps the familiar layout but adds tons of new features. You get Bedrock support now, full SNBT support, undo and redo, drag and drop, multiselect, and way more. It’s called Studio to make it sound fancier than it actually is.

Key Features

File Support

NBT Studio can read and write multiple NBT formats:

• Java NBT files like level.dat and player data
• Java region files (.mca and .mcr) with full world data
• Bedrock NBT files including .mcstructure files (little-endian NBT)
• SNBT files (the text format used in commands)

You can load a file in one format and save it as another. Open an SNBT file from a command and export it as a Bedrock structure file if you want. NBT Studio also lets you create blank NBT files from scratch. Press Ctrl Alt V to paste SNBT data from your clipboard and make it a new file.

SNBT Support

The whole app is built around moving data between text and structured formats. SNBT is the text format you see in commands and datapacks.

• Open SNBT files directly or create new files by pasting clipboard data
• Add tags as SNBT anywhere in your document. The parser figures out the type automatically
• Edit existing tags as SNBT. You can change entire compounds or single tags
• Copy, cut, and paste operations save tags as SNBT text to your clipboard

Easy Tag Editing

Working with NBT data doesn’t have to be painful. NBT Studio has shortcuts and features that make it faster:

• Create and edit tags with one dialog instead of two separate steps
• Hold Shift while adding a tag to skip the dialog and auto-name it
• Edit byte, short, int, and long lists in hex format like arrays
• Drag and drop tags to move them between parents
• Press Enter to edit a selected tag, Space to expand or collapse it
• Ctrl Space expands everything at once
• New and improved search with regex support and select-all matching
• Undo with Ctrl Z, redo with Ctrl Shift Z
• Right-click files to save or open in File Explorer
• Right-click container tags to add child tags
• Files show an asterisk when they have unsaved changes

Getting Started

First time using NBT Studio? Here’s what you need to know:

The app opens with a file browser on the left and an empty right panel. To start, open an NBT file. You can navigate to your .minecraft/saves/worldname folder to edit world data, or open any .nbt, .dat, or .mcstructure file.

Once a file is open, you see the NBT tree structure. Click the arrows to expand containers. Click on any tag to select it. Right-click to see what options are available. For basic editing, double-click a tag or press Enter to open the edit dialog.

If you’re working with command data, copy the SNBT from your command, then press Ctrl Alt V to paste it as a new file. You can edit it and copy it back as text when you’re done.
