Hi David, Actually, I don't use EDG for SS import at all. It is too limiting, especially when the need is repetitive. Thus I'm using TBC directly and I would have expected TBC to properly handle spreadsheets with missing column headers. I am writing my own construct queries and will use SWP or SPARQLMotion to iterate over the set of files.
Should I expect TBC to handle this import correctly?
