Use *ToExpression* to convert character strings into regular Mathematica
expressions. For instance,
In[1]:= data = {{"2", "3"}, {"1", "2"}}
data // FullForm
data = ToExpression[data]
data // FullForm
Out[1]= {{"2", "3"}, {"1", "2"}}
Out[2]= List[List["2", "3"], List["1", "2"]]
Out[3]= {{2, 3}, {1, 2}}
Out[4]= List[List[2, 3], List[1, 2]]
