How delete last bit (LSB)

I have array with bits in each row and in one column. Now I ned to delete LSB (parity bit) and then assemble all 7 bits back together and split them in parts by 8 bits.

My idea was to put bits in matrix and then take from matrix first 7 columns. Problem is that I don't know hot put each bit in his own column. Next problem is how to convert this in bytes.
