Is it possible to import a BPMN 2.0 XML into Visio?
The internationally standardized BPMN 2.0 XML format was created for the exchange of BPMN 2.0 diagrams, so that it is possible to exchange diagrams across platforms.
Visio does not natively offer such an import function.
However, there is the option of using commercial plugins for Visio. Unfortunately, Signavio cannot offer any support for this as this is not its own product.
Alternatively, you would have to request an import function from MS Visio.
