Multiselect fieldlabels

I use a 3pd tool to generate reports in Excel format.
I want to include some multiselect fields in the report, where I use both 'fieldtitle' and 'fieldlabel'.
In my report these fields displays like 'AR|*|SE' (fieldtitles) and I want to replace them to fieldlabels.
I guess the answer is somewhere in the CB code how to convert fieldtitle to fieldlabel on output, but I cannot find where.
Could you please give a hint?

Thanks.

We use PHP to explode the field value by |*| which gives an array of values selected. They're then matched with value for their label in the _comprofiler_field_values table. I've no idea what code usage you've access to in your reporting extension.

Thanks. Yes, I expected that PHP was used.
I use Alter Reports which can handle PHP on field level.
I think your method is possible to use, but my programming skills is not enough to create this function from scratch.

See getField of CBfield_select_multi_radio in components/com_comprofiler/plugin/user/plug_cbcore/cb.core.php as that's where the field values are turned into labels for display purposes.
