I have an excel spreadsheet with data set up in four different columns.
Sample data below:

Start 42, 43 56, 56 Finish
Start 12, 34 45, 45 Finish
Start 45, 56 78, 34 Finish
Start 45, 45 42, 43 Finish
Start 78, 34 12, 34 Finish
Start 45, 67 96, 23 Finish
Start 96, 23 45, 56 Finish
Start 56, 56 45, 45 Finish
Start 78, 34 78, 34 Finish
Start 12, 34 45, 56 Finish

I need to export those four columns of data to a text file, but need it to
end up in the the following format, with each cell on the next line:

Start
42, 43
56, 56
Finish
Start
12, 34
45, 45
Finish
Start
45, 56
78, 34
Finish

I'm currently using column Q-T on a sheet named "Data". Each week there is a
different number of rows, so I just need all rows containing data to be
addressed. Can anyone help? Thanks!
