I've been trying to create a plugin in QGIS that browse an excel sheet containing XY coordinates (points) and convert them (automatically) to a shapefile (polygon on this case). If done manually, I would add the data from the CSV file and link the points one by one to get a polygon. But am trying to automate this procedure for the users by creating this plugin.
My first question would be : is this even possible ? If so, can someone please indicate how it could be done, expecially the python code that can be used.
