I feel that this would be the most useful way of achieving my goal, but can't seem to get over the final stage.
I'm using the following formula on my data, pulling table data row by row into a column.
=INDEX($A$1:$F$9,INT((ROW()-ROW($G$1)-1)/COLUMNS($A$1:$F$9))+1,MOD(ROW()-ROW($G$1)-1,COLUMNS($A$1:$F$9))+1)
My Data looks like this, purely for this example.

So the formula works across row 1, then row 2 and so on.

What I am looking to do, is in the same format as this functionality, is only return the value from every 3rd cell. For example returning the below result.
[TABLE="width: 64"]
<tbody>[TR]
[TD]R1,C1
[/TD]

[TD]R1,C4

Essentially I need to repeat this process in another column to have a start point of B1, and then C1 to return every 3rd value in H + I respectively.

I will need to apply this to a 90 column table, reducing to 3 columns.
Any assistance would be appreciated.
