Comparing two excel files with different column names

Hi I want to compare 2 excel files which contains different column names like from one excel file I will choose one column an divide it by 12 whatever output will come I want to check in second excel file and if it will get matched then status column should get updated.

Hi @Deepti_Kadam ! :grinning_face_with_smiling_eyes:
Would you mind sending us a sample ? And explain what is the column in the sample that is split in 12 + an output of what you would like to see ?
