I am not able to export data from one of my form in CSV format. In Aggregate, I select "export" and I choose "CSV file", but I get a file in binary data. This is only happening with one of my form. Could you please help me with that?
Hmm, my guess is that your total submission size is very large and so you are running out of memory when building the CSV (can happen on App Engine) or there is some minor corruption in your database and that is causing an error that is blocking CSV from being built.
The fastest way to fix both issues it to try using ODK Briefcase to download your data. It'll download it incrementally so you don't run into the memory problems and if you there is corruption, it'll throw an error message which will be useful in finding and fixing the corruption.
