Task Pane Add-in: Equivalent of Document.getFileAsync method for Excel 2013 Desktop? RRS feed

  • Question

  • I am developing a Task Pane add-in for Microsoft Word, Excel, and PowerPoint desktop. I would like to have the ability to read the entire contents of the file and save it as a new document to a third-party application. Microsoft Word and PowerPoint support the Document.getFileAsync method to get the entire contents of a file; however, Excel desktop does not seem to support this functionality. Excel Online does, and I can actually use that method to save a new Excel file to my third-party app. Is there any way that I can get the contents of an Excel file using a desktop Add-in in order to create a new file?

    I am using Microsoft Office Home and Business 2013 to test.

    Thank you.
