Sample for Data driven automation testing

Can somebody please provide a sample real time project that uses excel as test data source?
I would like to have a sample that shows how the test cases are split into folders logically.
Also any additional sample that writes test results/output to another excel file during the run, is appreciated.

@rpn_mail ,

You can do this. Please create a common component to read excel data and call this into GIVEN section to read all the value and assign back to your test cases.
