    This might work for you (GNU sed):

    sed 's/\s*//;:a;s/,\(.*|\(.*\)\)/\2\n\1/;ta;s/|//' file

    Explanation:

    1. s/\s*// remove whitespace at the front of the record.
    2. :a;s/,\(.*|\(.*\)\)/\2\n\1/;ta replace each , by the last field and a newline
    3. s/|// remove the |

    To preserve whitespace use:

    sed -r 's/(\s*)(.*\|)/\2\1/;:a;s/,(.*\|(.*))/\2\n\1/;ta;s/\|//;s/(\S+)(\s+)(\S+)/\2\1\3/g' file
