I have a large variable that I want to export out of Matlab;
Name Size Bytes Class
NewDataSet2 756071x9 1167474054 cell
When I try to export it using:
writecell(NewDataSet2,'myDataFile.csv')
I get this error:
Error using writecell (line 117)
Nested cell arrays are not supported.
Any ideas on how to get this variable out of matlab and into a file (such as a text or excel file)?

It depends on what the contents of the cell elements is. Posting just the size does not allow to know this. Perhaps all you need is:
data = cell2mat(NewDataSet2)

How can I determine the contents of each cell?

@Jessica: Are you sure that you have to store such a large set of data in a cell array? This is rather inefficient. Please post a small example of the data. Then suggesting a solution is not based on pure guessing only.
If "determine the contents" means to get the class of the data:
cellfun('isclass', C, 'double')
cellfun(@class, C, 'UniformOutput', false)
