We present our calculated data including energy levels, radiative decay rates and effective collision strengths for all the transitions among the 32 fine-structure levels arising from the 18 lowest LS states of Na-like iso-electronic sequence, i.e. those with configurations: 2p(6)3l (l=s,p,d); 2p(6)4l (l=s,p,d,f); 2p(6)5l (l=s,p,d,f,g); 2p(6)6l (l=s,p,d,f,g,h). The effective collision strengths at 13 temperatures ranging from 2x10^2(q+1)^2 to 2x10^6(q+1)^2 K, where q is the residual charge of ions, i.e. Z-11, have been calculated using the ICFT R-matrix method. The data format adopts ADAS adf04 format, see the file at website http://www.adas.ac.uk/man/appxa-04.pdf
