PRN solution works only for simple data in the cells, for me it cuts only first 6 signs from 200 characters cell.
These are the main file formats in Excel 2007-2016, Note: In Excel for the Mac the values are +1
51 = xlOpenXMLWorkbook (without macro's in 2007-2016, xlsx)
52 = xlOpenXMLWorkbookMacroEnabled (with or without macro's in 2007-2016, xlsm)
50 = xlExcel12 (Excel Binary Workbook in 2007-2016 with or without macro's, xlsb)
56 = xlExcel8 (97-2003 format in Excel 2007-2016, xls)
From XlFileFormat FileFormat Property
Keep in mind others FileFormatNumbers for SaveAs method:
FileExtStr = ".csv": FileFormatNum = 6
FileExtStr = ".txt": FileFormatNum = -4158
FileExtStr = ".prn": FileFormatNum = 36
