Thanks Chris!
Now I am way down the rabbit hole.
Question: Does that mean that I cannot use the libxl.net.dll in the Appeon client?
Question: If I do go via web service, how do I get the spreadsheet to where it needs to be to get processed and how do I get it back to the client with entries via libxl.net.dll?
Question: Can I have the client save the spreadsheet as comma delimited and simply import into a datawindow for processing?
Thank you,
Paul
