VSSM Viewer API for Android - Render Visio Macro Stencils

VSSM files are macro-enabled Visio stencils, introduced with the other XML-based Visio formats in the 2013 release. They bundle master shapes with VBA macros that automate shape behavior, which keeps them tied to desktop Visio on Windows. An Android device cannot open them natively, and macro-carrying files are a security concern on every platform.

Rendering through GroupDocs.Viewer Cloud avoids both problems. Its REST API answers with the stencil as HTML, PDF, JPG or PNG, and an Android app shows those static pages while the original file is never opened by Visio on the device.

Integration follows the usual Android path: the Java SDK from Maven or Gradle, code samples for a first request, the API Explorer for trying endpoints, and a free trial for evaluation. Individual pages may be rendered one at a time, and password-protected files are supported.

For a single stencil, the free GroupDocs.Viewer app works in any browser without setup. One integration covers the complete Visio family and more than 180 formats overall, which suits archives of mixed diagrams.
