PHPSpreadsheet generates an error “Wrong number of

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 works perfectly fine (the left column on the pic below).

But if I'm using my web application to generate an excel report file (PHP, using CodeIgniter and Laravel). It displays an error "'Wrong number of arguments for INDEX() function: 5 given, between 1 and 4 expected'"

Here's my sample code snippet:

$code = "=INDEX(\$E\$4:\$E\$$occurance, AGGREGATE(15,6,ROW(\$1:\$$occurance) / (\$J\$4:\$J\$$occurance=M$top_cell), COUNTIF(\$M\$4:M$top_cell, M$top_cell)))";
$ews2->setCellValue("L$top_cell", $code);

I also have tried to use the setValueExplicit method but causes the excel file to NOT precalculate the code, it reads the code as a string

$ews2->setCellValueExplicit("L$top_cell", $code, DataType::TYPE_STRING);

NOTE TYPE_STRING is provided because if TYPE_FORMULA is also used, the same output mentioned at the top occurs

Here's what it looks like using the setCellValueExplicit

May I know the right solution or quick fix for this? Thank you very much in advance!

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
