Ability to open/replace workbook with Excel JS API in a similar way Word API can with insertFileFromBase64
We have a requirement to load a workbook from a remote source from within the add-in. User logs in, selects from a list and workbook template loads.
With the Word JS API we can load a template remotely using an AJAX call that returns the workbook as a base64 string and then insert the response into the current workbook using the replace option. AFAIK this doesn't exist for the Excel API and we download the workbook and then instruct the user to open from the download pane.149 votes

Authenticated O365 users shall not be prompted to login again when they want to use Word Add-In. At the moment any Word Add In secured using O365 directory need to prompt users to enter their credential again despite that they have logged in to O365.
The goal is to provide a better user experience with this single sign on.76 votes

In Excel API, I can't choose cells based if they have formulas or values.
In VBA, I can do that by using Range.SpecialCells method. Also, I can specify if I want to get only text values, numbers, errors and/or booleans.
Happy to report that some of the functionalities are already in the product (all the basics for creating Pivots!) and some in preview (i.e. advanced filtering, calculated fields) .
please see the details here.
