I'm trying to use var context = new Excel.RequestContext() in an Excel custom function as specified in the documentation, but the browser keeps complaining the Excel object does not exist. Anyone managed to call Excel object functions from custom functions ?

Thanks Matteo

  • Using Excel RequestContext in an Excel custom functions needs to config your Excel add-in to use a shared runtime. [Share data and events between Excel custom functions and the task pane](https://learn.microsoft.com/en-us/office/dev/add-ins/tutorials/share-data-and-events-between-custom-functions-and-the-task-pane-tutorial) shows how to config an add-in to use shared runtime. – xiaochun Jun 08 '20 at 06:44
