Import CSV module is mainly designed to import data from our own application only, but you can try to create your own CSV file containing coordinate data to be imported into our application. For this CSV file format, we only support WGS 84 Latitude Longitude coordinates, if your coordinates are in another coordinate system (eg UTM etc.) you can import using a TXT file.
Since CSV files have several separator types (comma, semicolon, space, pipe etc.), there is an option to choose the CSV file type when you import the file, make sure you know it before you import. If not, you can do trial by error.

The CSV file format must be in the following format (for point data):

For lines and polygons, coordinate data is stored in the standard WKT format, you can try exporting the line and polygon data you have into CSV format to learn the format.
