Flag a cell if it contains any of several keywords at once.
Copy this formula
=IF(SUMPRODUCT(--ISNUMBER(SEARCH(Words, A2)))>0, "Yes", "No")SEARCH checks each word in the Words range against the cell, ISNUMBER turns hits into TRUE, the double negative makes them 1/0, and SUMPRODUCT totals them — greater than zero means at least one keyword was found.
=SUMPRODUCT(--ISNUMBER(SEARCH(Banned, A2)))>0→TRUETRUE if the text contains any banned word.
Compare the count to the list length: …=COUNTA(Words) is TRUE only when every word is found.
