Importing Lab data

What are some of the ways you get lab data into Openground, particularly if the labs are not familiar with AGS format? Of course, manually entering data into Openground is one way, but what are the other ways you use? I am working on a excel workbook, that is really a collection of worksheets that I create with csv exports from Openground tables. The idea is to populate the excel workbook with lab data and then import as csv's. I wonder if this is the best way to do it. Thoughts?
