Exporting SSRS to TEXT not preserving actual format

I am using SQL Server 2008 R2. I would like to export SSRS file to .txt format.

I have added the following code to rsreportserver.config file.

<Extension Name="TXT" Type="Microsoft.ReportingServices.Rendering.DataRenderer.CsvReport,Microsoft.ReportingServices.DataRendering">
 <OverrideNames>
  <Name Language="en-US">TEXT</Name>
 </OverrideNames>
 <Configuration>
   <DeviceInfo>     
     <UseFormattedValues>False</UseFormattedValues>
     <NoHeader>False</NoHeader>
     <FileExtension>Txt</FileExtension>
     <OutputFormat>TXT</OutputFormat>
   </DeviceInfo>
 </Configuration>
</Extension>

After exporting, I can open the file in .txt format. But it is not preserving the exact SSRS format.
I need  .txt file in the following format.

"aa bb cc","dd ee ff","abcd 498798","","7232","141","808584001","19/02/2014","SGD","8947.08","","2549871000","SGD","2549871000","SGD","15","20","","","samantha.nio@expeditors.com","
