Column metrics difference one file to another

[faisal9999]

Hi , I have data in two files containing 100 column each....I want to get difference dynamically 

eg.. two file A and B

column1 - column1 

column2 - column2

I'll have to write every column name manually in formula tool

thanks for sharing but this was for one column suppose you have 100 column in both inputs total column 200 and and if you make difference of every column that means you have to apply 100 formula that means total column will be 300...I am looing for dymanic solution I want to save my time writing code in formula tool.

The workflow shared by @Raj is dynamic I believe.

I understand, I am looking for something like without using formula tool if you have 100 columns for bringing differences that you have to write 100 times that formula A - B..is there anything that I can save my time writing formula 100 times.
