Cyotek NBT Editor Simple to use NBT editor

You can open Minecraft data files - the editor supports uncompressed, Deflate and Gzip compressed files. However, it does not support Anvil or Bedrock files.

The editor supports all standard NBT tags, from the simple byte to the long array.

By default the editor operates in a dual pane mode, with compounds and lists shown on the left, and data values on the right. Alternatively, you can toggle single pane mode and display all tags in a single tree.

You can perform search and replace operations on both tags and values. There is also a Find All command which makes it easy to process search results.

The editor makes it easy to add and remove items from compound and list tags, and to edit individual items.

Need to store binary data in an NBT tag? Any tag apart from List or Compound can have its data edited as raw bytes and content loaded or saved to and from external files.

Any tag can be copied to the Clipboard and pasted back. Compound tags can also be exported to new NBT documents, or existing NBT documents imported into the tag hierarchy.
