I exported the attribute table of a shapefile to Excel (also saved in CSV). And I'm trying to add some columns to the table, then convert the table back to shapefile with the new columns. The shapefile is a network of roads, but I wasn't able to find a columns that contains x/y coordinates or WKT in the attribute table of the original shapefile.
I'm wondering how can I convert this exported and modified attribute table back to shapefile? I don't have ArcGIS so I think I have to use QGIS or other method.
