What are the CSV pre-requisites for using the converter ?

Hi, 

In my experience, the convertor works well with files that:

• contain as a minimum set of fields: an id, title, latitude and longitude (possibly in one field) 
• the geocoordinates can be either in seperate fields or in one field if formatted as such: "latitudelongitude"
• if they are in separate fields latitude and longitude should be concatenated in the convertor (final step: geocoordinates field) but a space character should be explicitely added by dragging the "custom text" field in between them and typing a space in the box
• In terms of formatting, delimiter can be , or ; and text can optionally be enclosed with double quotes
• Like you discovered, it's best to use UTF-8. Both LF and CR line-endings are recognized

Good luck!
