MCBE Structure Extractor

A browser-based tool to extract structure templates (.mcstructure) from Minecraft Bedrock Edition world files (.mcworld or .zip).
It automatically handles nested directories (e.g., iOS manual compression) and supports structure keys with the structuretemplate_mystructure: prefix.

Features

• Works entirely in the browser – no server required.
• Extracts structures saved with the mystructure: namespace.
• Preserves Unicode names (Chinese, Japanese, etc.).
• Packages all extracted structures into a downloadable ZIP file.
• Supports both .mcworld and .zip files.
