import sys
sys.path.append('/usr/local/google_appengine')
from google.appengine.api.files import records
from google.appengine.datastore import entity_pb
from google.appengine.api import datastore

raw = open('path_to_datastore_export_file', 'r')
reader = records.RecordsReader(raw)
for record in reader:
  entity_proto = entity_pb.EntityProto(contents=record)
  entity = datastore.Entity.FromPb(entity_proto)
  #Entity is available as a dictionary!
