Excel client : Do you know when Excel Client will not be supported ?

Ok, thank you for this quick answer.

So no emergency (contrary to the upgrade of report builder for the end of the month), but to plan it.

I'd recommend you start the migration ASAP so that you can manage the entire process better and do not run against time towards the end of the month(only 9 days left for the month to end).

I'm a little bit confused by this new answer.

Will Excel client still working after the end of this month or not ?

I've understand that is not the case and the mandatory upgrade concerns only Report Builder. 

Let me rephrase my previous response:

Why not upgrade to the latest version of Report Builder and continue working without worrying about when ExcelClient will be discontinued? This way you can continue to work with the latest offerings and enjoy more benefits from the newer version(unless there is a strong reason behind why you'd not like to migrate to a newer version). Hence as Devinder mentioned in his previous response :

ExcelClient has been removed from the SiteCatalyst 15 interface, however still works with existing v14 functionality. There are no current plans to continue updating this product; it is recommended to use ReportBuilder instead.

Hope this clears your doubts with respect to what I was trying to say.

Now It's clear :)

Thank you a lot for your quick answer.
