Hi:
You mean ODS TAGSETS.EXCELXP??? not OBS???
At any rate, I'm not sure I have ever seen labels disappear when I didn't want them to. What breaks are going away??? Do you have multiple tables created by PROC TABULATE. The default TAGSETS.EXCELXP behavior is to make one worksheet for each table. Or, do you mean the SAS Title statements go away? With TAGSETS.EXCELXP, the titles get put into the worksheet Header area (by default).
This is a useful paper about using ODS TAGSETS.EXCELXP:

Otherwise, for more help, you might see whether you can duplicate the behavior using sashelp.shoes or sashelp.class data and then post your code here with a description of -exactly- what's happening, like "the label for NAME is disappearing when Excel opens the file" or "the title statement is going away".
