Steps for converting CFG into CNF. Step 1: Eliminate start symbol from the RHS. If the start symbol T is at the right-hand side of any production, create a new production as: S1 → S. S1 → S. Where S1 is the new start symbol. Step 2: In the grammar, remove the null, unit and useless productions.

For a given grammar, there can be more than one CNF. CNF produces the same language as generated by CFG. CNF is used as a preprocessing step for many algorithms for CFG like CYK(membership algo), bottom-up parsers etc. For generating string w of length 'n' requires '2n-1' production or steps in CNF.
