Hi @jkorattiyil - You'll want to write a Formula to REGEX_Match the two columns putting in the pattern from Column A and selecting Column B. I've attached a sample workflow using your first example.
Are these values in Column A always in the same format or varying formats?
Thank you for your response! However i an not abel to open teh workflow, now sure is it due to any version difference. Can you please type teh formula. Yes, the column A fomrat will always remain same.
