Output data in different lines for header and line item

Hello experts,

My source data is H-1 H-1 H-1 H-1 L-1 L-1 L-1 L-1 L-1 L-1

                           H-1 H-1 H-1 H-1 L-2 L-2 L-2 L-2 L-2 L-2

                           H-2 H-2 H-2 H-2 L-2 L-2 L-2 L-2 L-2 L-2

where H is the header fields and L is the line item fields, so header and line item in one line

Now my requirement is such that

                           H-1 H-1 H-1 H-1

                                                    L-1 L-1 L-1 L-1 L-1 L-1

                                                    L-2 L-2 L-2 L-2 L-2 L-2

                           H-2 H-2 H-2 H-2

                                                    L-2 L-2 L-2 L-2 L-2 L-2

Header data in one line, and corresponding Line items in the next line,

How do i achieve this.

Thanks and regards,
