Вы можете сделать это так:
=ARRAYFORMULA(QUERY(UNIQUE(TRIM(SPLIT(TRANSPOSE(SPLIT(QUERY(TRANSPOSE(QUERY(TRANSPOSE(
IF(D2:K<>"", "♦"&ROW(A2:A)&"♥"&D2:K, )),,999^99)),,999^99), "♦")), "♥"))),
"select count(Col1) where Col1 is not null group by Col1 label count(Col1)''", 0))
или как это:
=ARRAYFORMULA({
COUNTUNIQUE(D2:H2);
COUNTUNIQUE(D3:H3);
COUNTUNIQUE(D4:H4);
COUNTUNIQUE(D5:H5);
COUNTUNIQUE(D6:H6);
COUNTUNIQUE(D7:H7)})
