Please teach me.

I've updated the patch's comment too.

Updated patch to add commas between grouped items.

This last patch works well for me. It does add a trailing comma to the end of the list of values in the field though.

It's a new patch

The patch does not seem to work for me.
Multiple values in fields generate as many lines.

+1 for this issue. I have a field where multiple tel. numbers can be saved. I cannot get this module do something reasonable with it. If I check grouping then the 2nd, 3rd values generate empty lines containing only the 2nd, 3rd tel. number. If I uncheck grouping then the whole lines are multiplicated. I'd like to concatenate the multiple values for example, or generate additional columns for them in the xls.

Any update on this?

Thanks for this patch (#6). In my situation it was really only needed for one particular report, but I realize that all views bonus pack XLS reports with multiple values generated will be affected. We'll see. Thanks again.
