This is kind of an annoying thing to do deal with. If you have data that is nested several levels deep and you're not always sure what level the data will be at, then I don't think my suggestion is the way to go. But if you know it will always be Level 1 will be a single Collection field where it looks like 'Row 1 of 1' in every row, then you can loop through that and extract it into a normal collection of data.
You'd loop through with Loop stages on the 0_Results collection, and then use some method to add the row to a new collection like [0_Results.JSON:Array] in a calc stage or I suppose you could append rows to collection (Collection manip VBO).
It sounds like you were on the right track, but copy rows wouldn't be the way to go because it overwrites the data in the output collection. Use the Append action in the Collection Manipulation VBO.
You could certain go the route that others suggested and convert to JSON instead. That would likely run much faster than looping through all the rows to extract the nested collections. So it's really up to your preference.
