title: Transfer binary data (image etc) in a CSV file
body: <p>I have some binary data to transfer in addition to some other metadata information stored as string, number etc. The binary data I have is image files stored as a blob column in the database, I want to include the blob column in the csv file and store the <strong>csv</strong> file in filesystem or sftp server, I guess it does not matter where it is stored.</p>
  
  <p>How can the binary data be stored as another column in the <strong>csv</strong> file? Is this a good practice to transfer the binary data this way? </p>
