Converting a .jar (Java Edition mod) to a .mcaddon (Bedrock Edition add-on) is not a simple file rename. It is a platform translation—moving logic from Java (PC, complex, flexible) to JavaScript/JSON (cross-platform, sandboxed, restricted). This report outlines why one would attempt this, the technical anatomy of the conversion, and the creative workarounds required.
You cannot directly convert a .jar to an .mcaddon with a magic button. But you can manually port the mod’s assets, data‑driven features, and (with significant effort) its custom logic using Bedrock’s JSON and Gametest scripting.
