Hi,
I find Arcgis for Excel useful but there are two things that changed after the latest update.
The first option is to select features on the map and export the selected feature to a new Tab in the same Excel document. This function is gone since the latest update.
I also find it difficult to find the right coordinate system when adding data, it would be useful to make it easier to search for coordinate systems or to add favorites.
I hope this will be changed in a future update.
Best regards, Jurgen Rotteveel
