Thanks for your response, it was very helpful. I did see the mention of columns starting with "csv_" but I hadn't used the right field names. Now with your explanation everything worked wonderfully!!!
except for a field which is supposed to store a google maps link. using the query you suggested I saw that the actual content of that field is not a regular url link to GMaps but something like this:
where the values for a, s, and the other s seem to change depending on the map link. I tried importing only the link but, of course, it did not work well (=at all), only when using whole string it gets imported properly. I'm having problems researching this also because I've got no idea what it could be called.
So I cannot import data to this map field because I don't know how to deduce/find this additional data. Would you know how I can create this for a different map link, or where I can find more information about this and possibly (=remotely) figure it out?
Thank you so much!
