Office Add-in Development Community (PnP) – June 2019 update

Office Add-ins team

We’re excited to announce two new solutions for Office Add-ins Patterns and Practices. These were recently put together for the Excel custom functions feature that was released to general availability (GA) on May 6.  

Custom function batching pattern 

If your custom functions call a remote service, you may want to use a batching pattern to reduce the number of network calls to the remote service. This is useful when a spreadsheet recalculates, and it contains many of your custom functions. Recalculate will result in many calls to your custom functions, but you can batch them into one or a few calls to the remote service.  

Use storage to share data between custom functions and the task pane 

If you need to share data values between your custom functions and the task pane, you can use the object. Custom functions and task panes do not share the same runtime and cannot access the same data. saves simple key/value pairs that you can access from both custom functions and the task pane.

About Office Add-ins Patterns & Practices (PnP) 

Office Add-ins PnP is a Microsoft led, community driven effort that helps developers extend, build, and provision customizations on the Office platform the right way by providing guidance and help through official documentation and open source initiatives. The source is maintained in GitHub where anyone can participate. You can provide contributions to the samples, reusable components, and documentation. Office Add-ins PnP is owned and coordinated by Office engineering teams, but the work is done by the community for the community. 

You can find code samples for Office Add-in development in the Office Add-ins PnP repoSome samples are also documented in the Office Add-ins docs, such as Batching custom function calls for a remote service. 

SharePoint PnP 

Office Add-ins PnP and SharePoint PnP are both related community driven efforts. SharePoint PnP provides community solutions for developers building on SharePoint.  For more information about SharePoint PnP, see
