Hi:
In this previous forum posting:

the poster was using TAGSETS.EXCELXP and SAS 9.1.3 and successfully got his credit card numbers rendered as text.
I wonder whether you have the correct tagset template for the ExcelXP tagset installed. In the posting, it was the ExcelXP v1.37 tagset that gave the correct results. If you are not using this tagset template version number to create your output, you may wish to work with Tech Support to find out what the current tagset template number is and how to install it to see whether it gives the same results as the v1.37 tagset template.
This web site has the updated tagset templates:
