I'm trying to retrieve data from Google Spreadsheets with no success.
I've gone through this:
http://code.google.com/apis/spreadsheets/data/3.0/developers_guide.html#RetrievingTables
and this:
Simple example of retrieving JSON feeds from Spreadsheets Data AP
I already set my spreadsheet as public (even though it shouldn't) just to take authentication out of the equation.
I have no problem getting the data in Atom/XML. However when I pass the parameter alt=json, I get the following error message:
The spreadsheet at this URL could not be found. Make sure that you have the right URL and that the owner of the spreadsheet hasn't deleted it.
Any ideas why this is happening?
