Multi transpose from one column

Add an Index column

Add a custom column using Number.IntegerDivide to divide the Index Column by 4 (as you have groups of 4).

Add a custom column(name it Heading) using Number.Mod([Index], 4) to create the field which we will use for column headings.

Then remove the Index column

Then Pivot the Heading column (pick the original column for Values column and Don't Aggregate)

That's the method.  Have a go and I can help if you get stuck (There will be exact examples on this forum or the web too)
