Availability of Excel Web Add-Ins
Excel Web Add-Ins are available in the following versions:
- Excel for Windows Desktop (>= Excel 2013 SP1)
- Excel Online
- Excel for Mac
- Excel for the iPad
How to get Excel Web Add-Ins ("Installation")
There are 3 ways to make Excel Web Add-Ins available on a specific Excel client (incl. Excel Online):
- Adding from the Office Store ("My Add-Ins")
- Central deployment via Office 365 ("Admin Managed")
- Sideloading ("Shared Folder") -> only relevant for Developers
Please note that additionally to the central deployment a user can also add the data1.io Add-In from the Office Store. In this case the button Show Taskpane will be shown double:
Both buttons open / refresh the same Taskpane, i.e. the Taskpane will not be doubled. We recommend to remove the Add-In from the Store in order to have only one Button.
Binding to the user account and rollout to all devices
It is important to realize that Excel Web Add-Ins are added to the user account that is connected with the Excel client where the Web Add-In is added and is then rolled out ("installed") to all devices of this user.
Therefore an Excel Web Add-In has to be added only once and will automatically "appear" on a new device and in Excel Online of this user.
Unfortunately it seems that this adding is done language specific. That means that the Add-In is bound to the user account together the current language of the Excel client (when adding a new Web Add-In). Changing the language of Excel (resp. MS Office) on the client means that the added Web Add-Ins are not available under the new language (and have to be added again).
If the automatic rollout does not work on a device, then the user has to open the "My Add-Ins" section and "Add" the Add-In explicitly on a device (the Add-Ins are always shown in the "My Add-Ins" or "Admin Managed" section, but under certain circumstances they are not automatically activated on a device):
Context Menu and Reload
Every Web Add-In has a context menu which can be opened when hoovering tdhe right upper corner of the Taskpane:
The most important entry ist the Reload function which is usefull if the Add-In (which is technically a website / webservice) has to be restarted (you can also use the shortcut F5 or Ctrl+F5).
Client Update of an Excel Web Add-In
If a new version of the Excel Web Add-In is published into the Office Store, this forces Excel clients with an existing installation of the Web Add-In to execute a local update:
After clicking "Update Now" the new version of the Add-In is running (e.g. with changed buttons in the ribbon).
Please note that the program functionality is updated continously within the same version of the Web Add-In. Therefore, updates of the Add-In are quite rarely compared to the monthly release of the program functionality.
Removing an Excel Web Add-In
A Web Add-In can be removed ("uninstalled") for the client (more precisely: from a user account and all his/her devices) by simply clicking in the context menu of a button in the ribbon:
Of course a Web Add-In can also be removed in the "My Add-Ins" section of the "My Add-Ins" Dialog:
