Especially for this purpose there are XML-based formats.

There are no simple way of storing set of values (matrix) as a single value, each way will have some trade-off.

I've attached examples of Survey Monkey's export functionality. Their format seems to be very close to yours, except that they do properly list a grid of the x/y values for each survey that can be used for statistical analysis. Perhaps there is simply a bug in your intended export format as I assume they are also following industry standards.
