Hi,
Export to Excel facility is available for only one report i.e 'Salary Register' as you know already. But you can save the report as excel format. But we are customizing all the reports in such a way that the user can add/remove/align the fields. Even the user can create report according to his/her requirement by selecting the fields.
I hope that solution will help you. We will come back to you with an update very soon.
Thanks
