Question : Unmerge cell and split into rows

Hi dear Experts,

I've been searching for a while but could not lay my finger on a ready answer.
In attached sheet data is organized per row, some cells icontain merged data.
In order to work with that data those values should be unmerged and spllit into rows.
The relevant column is B. It has a pendant in column G. Merged data in other cells can be unmerged too if that would simplify things a bit.
I hope the example makes things clear, and also that this is possible.
Thanks.

Answer : Unmerge cell and split into rows

Assuming that you have headings in Row 1 for all the columns you car about, this seems to be working. It "unmerges" all of the cells. (The cells are not truly merged in the Excel sense, of course...)
