Anyone successfully create an Excel file from a Suitelet? When I review the XML generated, it is perfect, but it won't open in Excel. Is it Excel, or a N/file, N/encode thing? Thanks

the usual answer is use sheet js

Roger that. Will give that a shot. Also, that you made the initial response surprises me not at all, lol. Much appreciated!

its a little unusual for you not to have tried sheet js

Probably due to a state of sleep deprivation.
