An invalid XML file might be generated when you use the ExcelXP tagset in a Unicode session of the fifth maintenance release of SAS 9.4 (TS1M5).  When the invalid file is created, a Microsoft Excel dialog box error is generated, which prevents the file from opening in Excel.  This problem is most likely to occur when there are numerous variables in the data set that is being processed. 

There is currently no circumvention for this issue.  However, if you are using the third maintenance release of SAS^® 9.4 (TS1M3) or later, you can use the ODS destination for Excel, which does not have this problem.
