A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Enter below formula in cell A11 and copy to the right & down:
=OFFSET($A$2,(ROUNDUP((ROW()-ROW($A$11)+1)/2,0)-1)*3+MOD(COLUMN()-COLUMN($A$11),3),MOD(ROW()-ROW($A$11),2))
You may start at any cell, just replace $A$11 in the formula to the start cell. If you want to start at D2, enter below formula in cell D2 and copy right / down:
=OFFSET($A$2,(ROUNDUP((ROW()-ROW($D$2)+1)/2,0)-1)*3+MOD(COLUMN()-COLUMN($D$2),3),MOD(ROW()-ROW($D$2),2))
