In Excel 2003, if you execute the following vba snippet, you'll get a DSN-less connection to your Sage demonstration company and a QueryTable containing the company name of the data at that location.
ActiveSheet.QueryTables.Add( _
Connection:="ODBC;" & _
"Driver={Sage Line 50 v18};" & _
"DIR=C:\ProgramData\Sage\Accounts\2012\DemoData\accdata", _
Destination:=Range("A1"), _
Sql:="select Name from Company").Refresh
You should edit the snippet where it is highlighted in yellow to reflect your Sage version (e.g. Sage 2010 = v16, Sage 2011 = v17, Sage 2012 = v18, Sage 2013 = v19, etc ...)
Once the QueryTable is created, you can edit the datapath in the Connection Dialog to access other company data and edit the query to access other tables.
Happy browsing!
