I use MCONCAT (Laurent Longre's MOREFUNC.XLL). I often need to filter my
spreadsheet and work with only a portion of the data. I was hoping there was
a way to use the MCONCAT to concatenate only the "visible cells".

My spreadsheet looks like this:

ColA ColB
AB 123
CD 456
EF 123

If I filter ColB down to 123, I would like the MCONCAT to concatenate ColA
Values AB and EF.

Thank you for thinking about this.

Best Regards.
