Export SQL query result to CSV

I'm using sqlcmd to export a query result with two columns to csv. The simple query is:

SELECT DISTINCT
    CustomerGuid, CustomerPassword
FROM
    ServiceOrder
ORDER BY
    CustomerGuid

When I open the exported csv in Excel both customer and password are on the same column. Is it possible to split them into their own column using sqlcmd. My sqlcmd looks like

SQLCMD -S . -d BAS -Q "SQL STATEMENT" -s "," -o "c:\data.csv"

Thanks.
