Argument Mapper utility

Bring legacy maps forward.

Convert maps exported by the original standalone HTML app into the canonical .arg format used by the TypeScript app. Structure, colours, images, review work, versions, and essay content are translated—not merely renamed.

Drop legacy map files here

Use app JSON or .mup exports. You can convert several maps in one pass.

Choose map files

Supported input: legacy app JSON, app-aware MindMup .mup, and plain MindMup JSON

Converter version 1.0.0. The generated file is formatted JSON with a .arg extension and can be imported from My Maps in the TypeScript app.
