XMLData\Mapping
 

I am trying to save an Excel 2003 xls file as a xml data file, but get
an error:

Can not save xml data because the wookbook does not contain any xml
mappings.

I am able to save it as an xml spreadsheet. I am trying to convert the
spreadsheet to an xml file to import the data into another program. I
have the xml tags, the other program will be looking for. How do I get
this accomplished using excel?

TIA
