PHPSpreadsheet generates an error “Wrong number of arguments for INDEX() function: 5 given, between 1 and 4 expected”

Question

I tried to enter the following code in my excel formula bar directly =INDEX($E$4:$E$132,AGGREGATE(15,6,ROW($1:$30) / ($J$4:$J$132=M4), COUNTIF($M$4:M4, M4))) and wo

Answer 1

I have found out that the PHPSpreadsheet library for PHP is yet to allow the usage of the AGGREGATE() and complicated formulas/functions, so I had found another way around

By using this excel code

=INDEX(E$2:E$38,IF(M4=M3,MATCH(L3,E$2:E$38,0),0)+MATCH(M4,OFFSET(J$2,IF(M4=M3,MATCH(L3,E$2:E$38,0),0),0,COUNT(J$2:J$38)-IF(M4=M3,MATCH(L3,E$2:E$38,0),0),1),0))

I was able to traverse through my entire range and make sure that no duplicate publication names would appear
