Any ideas/hints you can think of?
How about looking into FNR % 3 for starters?

Is awk a MUST? Or would e.g. paste do as well?

Most importantly, you have been here for long enough to know the rule:
Show what you have tried, and when error messages, join them to your request...

So what have you tried so far?

Try:

xargs -n3 < file

You can experiment by varying the number and see what it does.
