import file .csv

I mean to show the shop on the map. is it enough to have the address as mentioned above or do i need to have long/lat ? thanks.

You dont need latitude and longitude.
the system will automatically convert latitude and longitude if kept blank.
please click on export csv button and then you can have the csv that you are looking for.
also i am attaching sample csv.

I just opened the sample CSV file and I can't find, where to insert tags. Is it possible to upload multiple tags within the CSV file?

@ EVOC
we have implemented the tag from joomla system.
for migration of tag you need to use joomla tag import system if available.
Our extension wont support any feature that conflict with core joomla features.
