[William Lisowski]

I agree entirely with wbuchanan in post #15. I would never use column numbers in code except as a one-time hack, or if I were trying to do something more general, precede the insheetjson with some error checking that - in this case - reads the json as text and compares the array in the first line - with the attribute names - to a stashed copy that represents the assumptions on which I based my code. And I'd still be uncomfortable. This isn't the way JSON is supposed to work, as post #15 points out. But again, my interpretation of the trace output in post #12 suggests that's the way insheetjson works for "array of array" JSON.
