[GIS] Importing polylines and polygons into QGIS from CSV

Question

I want to import a large number of polylines and/ or polygons into one one or more QGIS layers in order to plot the data. Each will only have simple attributes (e.g. name). I need to know:

1. The required format of the CSV file to enable step 2.
2. The command or plug in required to create a polyline or polygon layer in QGIS.

For information, the input CSV files are written by bespoke Excel VBA or by FORTRAN codes, so I have full control of these output formats. Essentially I'm looking for the polyline and polygon equivalent of the delimited text plugin.

Answer 1

You can use Layer > Add delimited text layer
