Hi David,
unfortunately, the data in the spreadsheet are confidential. I checked it for cell errors, but there were no matches found. Everything in the table seems to be okay. I tried with an other data pump nsf and with it the import works. I think, it would be great if you could "install" an error handler which checks the condition of the data which the current cell contains.
It think, this is the reason the crash causes.
BTW: I hope, you will give the DMA a robust data-reading engine for excel, because your tool is great!
Regards
Rudi
