Visio for the web and BPMN
At the time of writing this book, only Visio Plan 2 desktop is able to create, modify, and edit BPMN files.
However, the Visio team at Microsoft is actively working on extending Visio web with BPMN templates and also with capabilities to edit shape data in shapes, which would give you the ability to also create, edit, and modify any BPMN diagram file in Visio for the web – that is, the web portion of your Visio Plan 2 license.
Important note
Please ensure that you have the right Visio license. To edit BPMN diagram files, you will need a Visio Plan 2 license; a regular Plan 1 license will not contain the BPMN templates and not give you the ability to edit BPMN diagram files.
