I have a large spreadsheet that is downloaded from another site.

Is there a formula to group rows from 'header' to next header?

I need to group 4 rows and then the corresponding data for the header rows
which varying in the number of rows e.g.

Header group
Date
Service Code
Name

Corresponding data: next 5 rows
Next header (as indicated above) can have 25 rows, etc.
