In my attribute table there is a large number of fields. I want to export the data with selected fields.
How to do this in QGIS?

You can probably set up a graphical model to do all this if you are going to be doing this a number of times.
I could suggest a PyQGIS way of implementing this task.
# referring to a needed layer layer = iface.activeLayer() # creating a temporal layer from selected features temp_layer = layer.materialize(QgsFeatureRequest().setFilterFids(layer.selectedFeatureIds())) # specifying important fields needed_fields = ["id"] all_fields = [field.name() for field in layer.fields()] other_fields = list(set(all_fields) - set(needed_fields)) # getting indexes of other fields idx = [temp_layer.fields().indexFromName(field) for field in other_fields] # deleting other fields based on their indexes temp_layer.dataProvider().deleteAttributes(idx) temp_layer.updateFields() # adding temporal output to the map canvas QgsProject.instance().addMapLayer(temp_layer)
