About This NBT to JSON Converter

This single-page tool was designed after analyzing popular Reddit, GitHub, and marketplace requests for faster Minecraft NBT workflows. Many online converters either compress functionality behind paywalls or force uploads that slow teams down. Here you can drop any world, structure, or player NBT and get a well-structured JSON tree instantly. The parser handles Java and Bedrock variants, detects tag depth, and keeps everything private on your device.

The interface takes its cues from premium Kadence-inspired WordPress layouts, pairing rounded corners, soft gradients, and crisp typography with serious performance goals. We target a sub-2.5 second Largest Contentful Paint and sub-0.1 Cumulative Layout Shift so that even mobile creators get snappy feedback. Under the hood, the script is vanilla JavaScript with no heavy dependencies, meaning there is nothing extra to load when you are on a flaky connection or working offline.

We also benchmarked against the most mentioned alternatives on Minecraft forums and automation communities. Our unique tag insight panel, shareable permalinks, and clipboard-ready JSON give content creators, map makers, and mod pack maintainers the quick wins they kept asking for. The result is a trustworthy, modern, and accessible NBT to JSON experience.

How to Use the Converter

Drop a `.nbt`, `.dat`, or region file into the upload area, or tap to browse from your device. Compressed (gzip) saves are detected and decompressed automatically.
Choose whether to force Bedrock little-endian parsing or let the auto-detection routine decide between Java and Bedrock formats.
Review the generated JSON inside the live viewer. Use the smart insights panel to double-check tag counts, hierarchy depth, and parse timings before exporting.
Copy to clipboard, download as a prettified `.json` file, or create a one-click permalink that restores the exact output for teammates.

Tips for Faster Minecraft Data Workflows

Use the tag breakdown to catch unexpectedly large lists or arrays before they slow down command block systems or datapacks.
Enable base64 auto-decoding when grabbing LevelDB exports from Bedrock tools to skip manual conversions.
Combine the shareable permalink with documentation or issue trackers so collaborators can recreate your inspection steps instantly.
After exporting, run the JSON through your automated tests or schema validators to keep custom tooling in sync across mods and servers.
