How to use Data Driven loop for multiple Excel Sheet?

If I create separate Data Driven for each sheet, then I will have copy and paste all steps that should be performed inside Data Driven loop. This is not a good practice. If, in future, I have to modify a step inside Data Driven Loop, I will have to make changes in all instances of Data Driven Loop. If you know some solution, would it be possible for you to post a small algorithm for doing same?



Thanks in advance!
