Updates to Visio Web Access (also called "Visio Services")

Beginning September 30, 2020, Visio Web Access and its Web Part for SharePoint Online will no longer be available.

Visio Web Access (aka Visio Services) allows online viewing of Visio diagrams stored on SharePoint Online and SharePoint On-Premise.

  • Visio Services render Visio documents in a Web browser without having Visio or Visio viewer installed on a local computer

  • It supports embedding of Visio Web Access Web Part in SharePoint to let you add diagrams to a SharePoint page.

    • Embedded Web Parts can be linked to data sources so that when data changes, the visuals (shapes, text, etc.) change, too.

    • Web Parts can also be driven programmatically using the JS API.

Recommended steps for using Visio Web Services on SharePoint Online

Microsoft recommends that customers start upgrading to Visio for the web. Visio for the web enables high fidelity viewing, sharing, and collaboration on the web browser full page without installing the client for all Office 365 licenses. It also supports embedding Visio diagrams in SharePoint Online by using File Viewer Web Part and iFrames along with JS API programmability.

In addition, Visio for the web supports richer scenarios such as find, pan/zoom, and Power BI–integrated dashboards, among other things. Moving to Visio for the web allows you to take advantage of the latest product innovations and ensure latest performance and reliability improvements that come from the Visio product team.

Migration assistance

After the end of the support period:

  1. Visio files from SharePoint Online will continue to open in Visio for the web, but you won't be able to switch to Visio Services.

  2. If you were using the Visio Services Web Access for web page viewing, you'll need to resave your .VDW files into the new file format .VSD/.VSDX.

  3. If you were using Visio Web Access Web Part, you'll have to migrate them to the Visio Online File Viewer Web Part to embed Visio documents in SharePoint Online.

  4. If you were using Visio Services Web Access Web Parts with JS APIs, you will have to migrate them to iFrame with new JS APIs in Visio for the web to stop them from working.
