Hi pdog1967
This is one of the new file formats in excel 2007
See
http://www.rondebruin.nl/2007filesin2003.htm
This are the main formats in Excel 2007 :
xlsx = xlOpenXMLWorkbook (without macro's in 2007, xlsx)
xlsm = xlOpenXMLWorkbookMacroEnabled (with or without macro's in 2007, xlsm)
xlsb = xlExcel12 (Excel Binary Workbook in 2007 with or without macros, xlsb)
xls = xlExcel8 (97-2003 format in Excel 2007, xls)

I have created and saved several files in Excel. I then sent them to a friend
at a different company. I was then notified that they could open all of the
files that were .xls but the one that was .xlsx they could not open. How did
I get the file saved with the extra x, and what does that mean?
