I'm unsure where your data comes from, why it contains \n etc. Perhaps your problem is solved if instead of using columns and `text` you use the direct assignments of attributes to your string variable? Sth. like

    for o in current do {
        string objID = o."Absolute Number"
        string objText = o."Object Text"
        string objPrio = o."Priority"
…
 file <<"\n" objID "," "\"" objText "\"" "," "\"" objPrio "\"" …

if this does not work, please post an example of your data.
