SchemConvert
SchemConvert converts Minecraft schematic files among .nbt, .schem, .litematic and .bp formats.
What SchemConvert is
SchemConvert converts Minecraft schematic files among .nbt, .schem, .litematic and .bp formats. The formats correspond to different tools: .nbt is used by vanilla structure blocks, .schem by community programs such as WorldEdit and MCEdit, .litematic by Litematica, and .bp by Axiom for blueprints. It can convert multiple schematic files in one batch, and its listed placement workflow is export-only. SchemConvert is a free, open-source desktop tool for Linux, macOS and Windows, published under the GPL-3.0 license. Running it requires Java 21 or later. A release note mentions command-line conversion to .litematic. The project is hosted on GitHub. GitHub reports that the repository has no published security advisories and has not set up a SECURITY.md file. Its stated scope is focused on converting and exporting files in the supported formats.
