I regularly get sent a report that needs modifying to make it into a list so
that it can be analysed. I have found and used or recorded macros to get rid
of some of the problems but the final formatting is beyond me because I'm
more of an interested amateur than a pro.

The problem is that each record is on multiple rows and I need to get them
all onto single rows.

The format for each record is:
Header1, Header1, Header1
DetailsA, DetailsA, DetailsA, DetailsA, DetailsA
DetailsB, DetailsB, DetailsB, DetailsB, DetailsB
Header2, Header2, Header2
DetailsA, DetailsA, DetailsA, DetailsA, DetailsA
DetailsB, DetailsB, DetailsB, DetailsB, DetailsB
DetailsC, DetailsC, DetailsC, DetailsC, DetailsC

The is only ever one header row but there are any number of details rows.

I would like to get to:

Header1, Header1, Header1, DetailsA, DetailsA, DetailsA, DetailsA, DetailsA
Header1, Header1, Header1, DetailsB, DetailsB, DetailsB, DetailsB, DetailsB
Header2, Header2, Header2, DetailsA, DetailsA, DetailsA, DetailsA, DetailsA
Header2, Header2, Header2, DetailsB, DetailsB, DetailsB, DetailsB, DetailsB
Header2, Header2, Header2, DetailsC, DetailsC, DetailsC, DetailsC, DetailsC

I hope this makes sense and thanks in advance for any suggestions.

Cheers,
Mark
