Google App Engine: how to download datastore as XML or CSV

Question

I'm trying to download my data from App Engine. As suggested here, I'm using the following command to grab it as CSV:

appcfg.py download_data --filename=backup.csv --application=MyAppId --url=http://MyAppId.appspot.com/remote_api --rps_limit=500 --bandwidth_limit=2500000 --batch_size=100

But the resulting file is always a binary SQLite file, not CSV.

How can I get my data as CSV or XML?

Answer 1

Have you read the section of the docs concerning the bulkloader? It describes in some detail how to do bulkloading and how to set up the configuration file that describes how to translate between CSV files and your datastore.
