Mehdi HAMMADI - there are a few things you'll need in order to see the Data Type group in the ribbon. First, the feature is only available to Office 365 subscribers, so if you are using a one-time purchase of Office 2019, you will not see the feature. Second, you will need to have an English editing language enabled since the data in Data Types is only available in English at this time. Regarding the Algiers Stock Exchange, we do not support it at this time, but will take it in to consideration. You can view an up to date list of our supported exchanges here.
BoBoSlacke - is there anything specific about the Stocks data type that you feel is not stable enough yet, or are you waiting just to be safe? Regarding currencies, we're working on adding exchange rates in these forms (e.g. USDEUR) now and they should be available in the next few months. Apologies for this being confusing right now
Thanks for your comments!
James
