Use the address list as the data source for a Directory type mail merge in
the main document of which, you have a single row table with as many cells
as there are fields in the data source.  When you execute that merge to a
new document, that document will have a row of data for each record in the
data source.  Insert a row at the top of the table and into the cells in
that row, enter the names of the merge fields.  Then save that document and
use it as your data source, editing it as required.

You can open an OAL in Excel if you have that product.
