问题
I have this formula for counting matches in Contents!$B$2 in J4.
=ARRAYFORMULA(IF(NOT(REGEXMATCH(J4,
"\w")),0,SUM(COUNTIF(REGEXREPLACE(SPLIT(J4,","),"
[\s]",""),REGEXREPLACE(SPLIT(Contents!$B$2,","),"[\s]","")))))
The formula is in K4 but ideally, I want it to work right down J returning values to the relevant adjacent K. I tried this but it didn't work. Just filled the cell the formula was in
=ARRAYFORMULA(IF(NOT(REGEXMATCH(J4:J,
"\w")),0,SUM(COUNTIF(REGEXREPLACE(SPLIT(J4:J,","),"
[\s]",""),REGEXREPLACE(SPLIT(Contents!$B$2,","),"[\s]","")))))
I know I can just fill down but the issue is users inserting rows.
Thanks in advance for any assistance

=ARRAYFORMULA(IF(LEN(A2:A), IFERROR(VLOOKUP(A2:A,
QUERY(TRIM(TRANSPOSE(SPLIT(Contents!B1, ","))),
"select Col1,count(Col1) group by Col1", 0), 2, 0), 0), ))
