About This Tool

This tool provides a browser-based editor for Minecraft NBT and SNBT data. It allows editing, validation, and conversion between SNBT and JSON formats, focusing on accuracy and interoperability for mods, datapacks, and server configurations.
Conceptually, users supply SNBT or JSON input, the system parses it into a tree, validates each tag type, ensures proper nesting, and can convert the data to the alternate representation. Outputs are deterministic, well-formatted data suitable for direct use in code, datapacks, or configuration files. The tool targets modders, map makers, and server admins who require reliable data without manual guessing, and it supports nested compounds, lists, and array types with clear error reporting for easy debugging.
Unique value lies in robust type checking, bidirectional conversion, and a focus on data portability across Minecraft tooling ecosystems. Core features include parsing, validation, conversion, and pretty-printing; use cases include porting data between tools, correcting syntax errors in SNBT, and producing JSON-ready outputs for plugins and datapacks. This tool improves accuracy, reduces iteration time, and helps teams maintain consistent data formats across development and deployment stages.

How to Use

Provide inputs: paste SNBT or JSON into the input field.
Choose operation: validate, convert to JSON, or convert to SNBT.
Run transformation: press the calculate/transform action to generate outputs.
Review outputs: copy or export the resulting data and use it in mods, datapacks, or server configs.
Optional: adjust formatting or depth settings if available to tailor the output for your workflow.

Frequently Asked Questions

Find Quick Answers

What formats are supported?
The tool supports SNBT (stringified NBT) and JSON representations of NBT data. It can validate syntax, convert between the two, and produce a clean, serialized output for downstream use.
Can it handle nested structures and arrays?
Yes. The parser understands nested compounds and lists, including arrays for ByteArray, IntArray, and LongArray, and validates all tag types across depth levels.
Is my data transmitted to a server?
The tool is designed for client-side processing to maintain privacy. Data remains in the browser unless you explicitly export or share the results.
How are errors reported?
Syntax errors, missing braces, or type mismatches are reported with contextual guidance when available, enabling quicker correction and re-validation.
