Excel-based export with nicely laid out formatting rather than the current .CSV.

I believe it would be hugely useful to many of your users if you had a timesheet export function that generates Excel-formatted files. The .CSV export feature at the moment produces files with very unusable formatting (especially if you have extensive note taking in your timesheet). The formatting would be great if it looked similar to your PDF export but in an Excel file (many in the consulting world have to submit timesheets in Excel rather than PDF!).
