I believe that the simplest method is to sort on column A after highlighting
all your columns and rows containg data.
I assume each column has a heading !
Again, highlight ALL your data,
then - Data Subtotals and complete the boxes in the window : At each
change in 'a'
Use function 'sum'
Add sub totals to - tick column letters that you wish to sub total
Tick 'Summary below data' will give you a Grand Total
Click 'OK'
Hope this helps

I have a data set of 12 columns with 200 unique codes in Column A.
I would like to be able to automatically create subtotals for each of the
data columns sorted by Column A data.

Easy to do manually but don't know how to do automatically.
