How to generate excel reports in cucumber

Are you asking for Extent Reports?

If yes, you can refer module 27 for this.

Not extent reports, excel reports in xls.format. could you please help me

In extent reports, how all the test results details are shown, similarly i am looking for all those details to be shown in .xls format.

In this case, you need to use your own logic the write the report according to your need.

You can write the data in the XLS file, where you usually write the command System.out.println();
