Consider numeric data that has the form
{{{a,{b,c,d},e,f,g,h,k,{l,m,n},o}, ...},...},
where the first ... mean other similar rows, while the second ... mean similar structures. A toy example is

I export it using the following command:
Export["dat.dat", data, "Table"]
When importing, the structure becomes broken:

Could you please tell me how to fix exporting/importing such that the structure of the initial data would be untouched?
Edit. It turns out that exporting/importing in format "MX" does work.
