I'm not clear on what problems you had with exporting to csv.. (you can
also do a bulkloader --dump to just dump everything.. but that's really a
backup that can just be --restore(d) to another app or to your same app)
to export one of my kinds to .csv.. I just create a py file containing this:
# myKindExporter.py
from google.appengine.ext import db
from google.appengine.tools import bulkloader
class myKind(db.Model):
ID = IntegerProperty()
step = IntegerProperty()
thing = FloatProperty()
class myKindExporter(bulkloader.Exporter):
def __init__(self):
bulkloader.Exporter.__init__(self, 'stck',
[('__key__',str,None),
('ID',int, None),
('step',int,None),
('thing',float,None)
])
exporters = [myKindExporter]
Then I run this command (myApp folder must be where your app.yaml is):
appcfg.py download_data path/to/myApp --filename=myKind.csv
--config_file=path/to/myKind.py --kind=myKind
If you want more exploration on Bulk Exporting, go here (always read Nick
Johnson's blog for AppEngine illumination):

There are fancier things you can do... but the above is your starting point.
