Hello,
There are probably better ways, but the following is one solution:
orig = {{{a1, a2, a3}, {b1, b2, b3}}, {{a1}, {b1}}, {{a1, a2,
a3}, {b1, b2, b3}}}
Transpose[{Flatten[orig[[All, 1]]], Flatten[orig[[All, 2]]]}]
Out[452]= {{a1, b1}, {a2, b2}, {a3, b3}, {a1, b1}, {a1, b1}, {a2, b2},
{a3, b3}}
MapThread[List, {Flatten[orig[[All, 1]]], Flatten[orig[[All, 2]]]}]
is a slight variant.
And of course
TableForm[orig] gives a nice table of what is needed
